On the lookout for the simplest mods on your Honda CRF50 or XR50? Whether or not you’re simply wanting just a little bit extra energy, stiffer suspension, or a quick and comfy pit bike, you’ve discovered the proper article!

There’s a limiteless provide of aftermarket pit bike elements for the CRF50F, however this information solely covers the perfect ones that enhance your 50cc bike’s efficiency, security, and total consolation. You can begin with the free or low-cost mods, after which progress to costlier elements as your “CRF50 Construct” will get extra addicting…

Is the Honda CRF50F a very good grime bike to change?

There are a lot of completely different pit bikes you can improve with hop-up elements, however not all of them are constructed the identical. For instance, the CRF50 is a children grime bike that’s made for riders underneath 100 lbs, so it’s not solely going to be a tough journey if you happen to’re a teen or grownup, but it surely will also be harmful as a result of the inventory suspension will “backside out” and buck you off the seat if you happen to’re driving aggressively.

With that stated, the CRF 50 is definitely a very good grime bike to change if you happen to use improve the proper elements. For instance, if you happen to weigh over 100 lbs and wish to use it as a “play bike”, then I extremely suggest upgrading the suspension and chassis in order that it’s extra sturdy.

In comparison with a budget no-name model pit bikes, the Honda 50cc pit bike can be extra dependable as a result of it’s constructed with greater high quality elements, however it should nonetheless break simply if you happen to don’t make the suspension stiffer and reinforce the chassis/body.

Finest Free or Low cost Mods on your CRF50

Free or low-cost efficiency is tough to move up, so we’ll have a look at the perfect free and low-cost mods on your CRF50 first. Then I’ll cowl the perfect efficiency upgrades that price just a little bit extra.

Lightened Flywheel Mod

Eradicating materials from the flywheel is an efficient and free mod when you’ve got entry to a lathe or a machinist. It received’t add any horsepower to your CRF50, however it should enhance throttle response and permit the engine to rev up faster. 

The inventory flywheel is pretty heavy, so lowering the a number of ounces received’t have a lot of a unfavourable have an effect on. Nevertheless, since it should rev up faster, it should additionally decelerate faster on account of much less inertia (rotating mass).

CRF70F Carb Improve

Upgrading to a CRF70 carburetor is a comparatively low-cost mod as a result of you’ll find them used on eBay or get a low-cost knock-off carb on Amazon if you happen to don’t thoughts decrease high quality elements. The CRF 70 has a bigger carb, which is able to pull extra air by means of than the smaller CRF50 carb. 

Nevertheless, you’ll possible want all the CRF70 carb arrange together with the consumption manifold as a way to make it match correctly.

Warning: solely doing this mod will greater than possible lose bottom-end energy as a result of the 50cc engine has a selected carb dimension. 

It’s greatest to do a mixture of mods that work collectively to get the perfect outcomes. Extra on this later. 

Take away The Choke & Plug It

Eradicating the choke from a inventory carb is one other efficient and nearly free energy mod. The choke is a butterfly valve that opens and closes within the carb bore. 

Nevertheless, even when it’s closed, it nonetheless takes up some area, lowering the quantity of attainable air going by means of. 

The extra air you may get by means of the carb, the extra potential energy you may get. 

Upgraded Air Filter

With a purpose to get extra energy, you want extra air and gasoline. Gasoline can’t be correctly burned except there’s sufficient air or else it should run wealthy. 

Upgrading to a Uni 2-stage Pod Filter (Amazon) is an efficient solution to get higher throttle response, but it surely’s not probably the most dependable improve. Because it’s out within the open (as an alternative of being coated by an airbox), it’s extra prone to suck in additional grime and water.

This will trigger it to die and never begin and might even harm your CRF50 engine if you happen to preserve driving in mud and many sand. It’s undoubtedly a compromise when altering to a pod filter on any grime bike – they’re greatest while you’re racing or driving in “cleaner” situations with little to no mud and dust or water.

Your different possibility is to easily exchange the inventory filter with a clear new air filter (Amazon). The inventory CRF 50 filter can nonetheless get soiled from sucking in grime and leaves on the paths, so it’s greatest to wash or exchange it, which might additionally offer you extra energy in comparison with a grimy filter.

Gearing Swap

Need quicker acceleration? Swapping sprockets to vary the gearing is and straightforward and low-cost solution to make it really feel like your 50cc pit bike is quicker. 
The inventory entrance countershaft sprocket isa 14-tooth, so taking place to a 13T sprocket (Amazon) is an inexpensive solution to get just a little higher acceleration and response.

Altering the gearing doesn’t really change the torque or horsepower. It simply shortens the ultimate drive ratio, so it reaches the max RPM in every gear faster. 

The larger and extra highly effective the engine, the taller gearing you can also make use of as a result of it may pull it. Simply one thing to remember as you modify your CRF50. 

So if you’d like extra high velocity, you’ll be able to go as much as a 15-tooth on the entrance (Amazon).

Exhaust Tip

An affordable solution to open up your inventory exhaust is with a easy aftermarket exhaust tip (Amazon). The inventory baffle is pretty restrictive, so a extra open tip will promote extra circulation, supplying you with barely higher throttle response in addition to extra noise. 

Tuning the jets could also be wanted to appropriate a lean situation and get probably the most energy. I don’t suggest this mod if you happen to reside in a noise-conscience space as a result of it should make your CRF50 fairly a bit louder than the inventory exhaust baffle/tip.

Finest Efficiency Upgrades

There’s an countless checklist of attainable mods you are able to do to your CRF50, however we’ll simply undergo the perfect ones that truly enhance the efficiency. This contains suspension, engine, or body mods. 

Rear Shock Upgrades

The inventory suspension on an XR or CRF 50 can’t deal with the load of an grownup except you’re simply driving on flat floor. Even then a spring improve will enhance your journey and never backside out so simply. 

Cheaper shock spring

Going with a heavy obligation rear shock spring (Amazon) is an reasonably priced solution to stiffen the inventory rear shock, whether or not you’re an grownup or your child is beginning to journey quicker and the inventory suspension is just too gentle

Upgraded rear shock

When you have just a little more cash to spend, upgrading to a Fastace adjustable shock (Amazon) will provide you with a lot better efficiency over the inventory shock. Not solely is it a lot stiffer, however you’ll be able to alter the rebound damping for just a little extra management and luxury primarily based in your weight and driving model.

It’s going to make your rear finish sit just a little greater, so that you’ll wish to elevate your forks if you happen to haven’t already. If the suspension isn’t balanced then you definately’re not going to have the perfect traction and stability, which is able to make your CRF50F more durable to journey and extra prone to trigger you to scrub the tires out.

Entrance Fork Improve

For those who’re going to stiffen up the rear, you’ll must stiffen the entrance to steadiness it out.

Low cost fork springs & oil

Heavy obligation forks springs (Amazon) are comparatively low-cost and actually assist the inventory forks forestall bottoming. Fixed bottoming of the forks will end in harm to the forks or body, in addition to inflicting a better likelihood of crashing. 

It’s also possible to decelerate the compression and rebound damping to make your inventory Honda 50 forks stiffer with some heavier-weight fork oil (Amazon). It’s also possible to elevate the fork oil top to cut back bottoming, however all the time confer with your OEM service guide for min/max oil top settings.

Additionally, in case your inventory entrance forks are free, then you definately may must tighten or exchange the fork information bushings (Amazon).

Upgraded fork swap

Sadly, there aren’t any good high quality fork upgrades on Amazon as a result of they’re all low-cost in high quality and low in efficiency. With that stated, upgrading to a set of XR70/CRF70 forks is an efficient solution to get higher efficiency.

They require a barely mod to the brake, however in any other case are a easy bolt-on improve.

Reinforce the body

Talking of body harm, correct reinforcement is wise if you happen to’re going to be leaping your CRF50 or driving it aggressively. Since there isn’t any body cradle, the engine itself is the “help” for the body, so if it flexes an excessive amount of, the motor mounts will break. 

Including a easy BBR skid plate (Amazon) is reasonable insurance coverage. The body cradle helps the engine and the footpegs, so you’ll be able to journey more durable with out bending or breaking elements. 

Tall Seat

Pit bikes are known as pit bikes for a cause. They’re modified mini grime bikes, so that they’re actually too small for adults to journey comfortably – except you do modifications to make them taller or really feel larger. 

Changing the inventory seat with a tall seat (Amazon) makes a giant distinction, giving your legs just a little extra room to work with whereas driving. 

Large Pegs

The inventory footpegs are small and low efficiency as a result of it’s a little children grime bike. This will make it very straightforward on your foot to slide off and trigger you to lose management of the bike whereas driving.

Upgrading to wider footpegs (Amazon) offers you extra stability in addition to grip as a result of the enamel are sharper. 

Handlebars

Now that you simply’ve raised the seat, the handlebars are awkwardly low. Tall mini bars are an effective way to essentially open up the cockpit whereas being stronger than inventory, however taller bars means you want longer cables too…

That’s why Professional Taper presents a Tall Bar Package on your CRF50 (Amazon) that comes with all the things it’s essential to match and work in your Honda with out modification. You get the bars and a totally adjustable triple clamp that offers you a extra stable really feel in comparison with inventory, in addition to the throttle and longer cables you want.

Some shoppers have had hassle with the throttle meeting from it, so chances are you’ll not be capable of use it if these elements are of poor high quality. 

Triple Clamps

On the lookout for the perfect efficiency and sturdiness? Upgrading to a Professional Taper High Triple Clamp (Amazon) offers you higher energy and flexibility in bar mounting choices, permitting you to maneuver the bars to the place you need them.

Nevertheless, if you happen to’re upgrading to taller bars then you definately may as effectively simply get the full handlebars and triple clamps mount package (Amazon) from BBR or the Professional Taper package that I discussed above.

Exhaust System

Changing the inventory CRF50F is among the commonest modifications as a result of it’s straightforward, comparatively low-cost, and there’s huge beneficial properties… at the least in sound. Okay, yeah there’s some energy beneficial properties available as effectively with a very good aftermarket exhaust. 

A low-cost knock-off system (Amazon) might be had for near 50 bucks if you’d like just a little extra energy and extra noise.

For a better high quality exhaust system, you may get the FMF Powercore 4 (Amazon), which is able to usually match higher, sound higher, and make extra energy when correctly jetted. It’s an entire system that’s lighter than inventory and appears a lot better with a deeper sound, but it surely’s a lot louder than inventory and doesn’t include a spark arrestor.

FMF, Professional Circuit, and Two Bros make high quality pipes for the CRF50 if you’d like the perfect.

Excessive Compression Piston

Need extra energy however can’t or don’t wish to go larger on engine displacement? Including compression with a excessive compression piston (Amazon) is among the greatest methods to spice up torque and horsepower in your 50cc Honda pit bike. 

It’s nearly as dependable as inventory, and you may nonetheless run pump fuel (premium). For those who simply want to exchange the unique piston and rings, that is an reasonably priced choice to get a litle extra energy, particularly if you happen to add an exhaust and correctly tune the carb.

Massive Bore Package

An 88cc huge bore package (Amazon) is among the greatest bangs on your buck relating to including horsepower to your CRF50. 

For about the identical worth as an exhaust system, you get nearly double the engine displacement. The BBR huge bore package (Amazon) comes with all the things you want, from the cylinder and piston to the gasket package. 

In case your 50 wants an engine rebuild, otherwise you simply need fast and reasonably priced energy, an 88cc will get you there. 

Full engine improve

Possibly you simply desire a easy bolt-on engine that will provide you with far more energy. Right here’s your reply – a Lifan 150cc engine package (Amazon).

It comes with a model new engine, CDI, gaskets, consumption manifold and kickstart lever to suit onto your inventory CRF50 body. Cautious, as a result of if you happen to nonetheless have the inventory gearing and suspension, this engine will wish to wheelie and overpower you rapidly!

Heavy Obligation Clutch Springs

A inventory Honda 50 is constructed for a 50lb child. For those who weigh 125lb+, you’re going to tax the clutches if you happen to’ve upgraded the engine for extra energy. 

Sure, it’s a semi-automatic transmission, that means there isn’t any guide clutch. However there’s nonetheless a clutch, and the inventory springs can solely maintain a lot stress.

The extra energy you add and the heavier the rider, the faster the inventory clutch will fail. Upgrading to some heavier obligation clutch springs (Amazon) will assist get rid of this downside. 

Cylinder Head Breather Package

This mod is reasonable, however solely obligatory when you’ve got a giant bore or stroker package in your CRF50. It merely exhausts the additional crankcase stress that the larger displacement engine places out. 

Getting The Most Out of Your Massive Bore

An engine should work in unison with the consumption and exhaust to provide the simplest energy. When you have a giant bore with a small inventory carburetor and exhaust, it’s going to be choked up and restrict your potential efficiency beneficial properties. 

Upgrading to a much bigger carb with correct jetting and an aftermarket exhaust will actually let the larger engine breathe and run at it’s greatest. 

Skinny Copper Head Gasket

Are you a part of the 1% that wishes each energy mod attainable? When you’re rebuilding the top-end, use a skinny copper head gasket to bump up the compression just a little extra. Extra compression equals extra torque to make your CRF50F speed up quicker. 

Camshaft

The camshaft on a 4 stroke is among the most vital items to constructing a robust engine. In order for you most torque with a easy powerband, going with a max raise racing camshaft will destroy your low-end energy. 

Retaining the inventory CRF50 cam in a extremely modified engine will drastically restrict its potential and it’ll fall flat at greater RPMs. 

“Massive” Cylinder Head

The cylinder is the opposite huge hyperlink to piecing collectively the final word 4 stroke engine. Clearly the inventory head is severely limiting how a lot air can circulation by means of it with out main porting work. 

To avoid wasting time, you’ll be able to merely bolt on an aftermarket cylinder head package (Amazon) that’s already designed to work with a modified CRF 50. This one comes with an entire huge bore top-end, carb and consumption to offer you a large improve in efficiency in a single package deal.

Stroker Crank

Going all out in your pit bike construct? A stroker crankshaft is the final huge piece to modifying your inventory CRF or XR 50 engine. 

It requires extra work to get to the underside finish, but it surely’s simply what you must do for max engine dimension. 

Full Race Package
