Yamaha MT-10 SP Venture Bike – Replace 1

It’s been a couple of month since we launched Bike.com’s 2022 Yamaha MT-10 SP semi-long-term venture bike. In case you forgot the premise of this entire factor, Yamaha provided us the chance to hold on to an MT-10 SP for an prolonged time period, and since I’ve a delicate spot for the bike, I made a decision to present it some tasteful upgrades to deal with some key weaknesses whereas additionally unleashing some trapped potential. The purpose right here is two-fold: first is to see what the bike may do with some easy upgrades. Second is to not break the financial institution whereas doing so as a result of in any other case, you may simply go purchase one of many European rivals that may most likely nonetheless spank this MT, inventory. 

Previously month I’ve put in the upgrades and even taken the trusty MT to the observe and ridden it on the streets somewhat. Learn on to get my tackle every improve, starting from ease of set up to real-world impressions.

Brakes

First up, the brakes. EBC was form sufficient to ship its HH sintered brake pads, that are its most aggressive. For under $80, it’s an enormous worth for dramatic braking efficiency, particularly over the inventory pads. Set up is tremendous straightforward, too, as you simply have to take away a clip, slide the previous pads out, slide the brand new ones in, and reinstall the clip. It’s a simple five-minute job with large outcomes. After all, don’t overlook to take some high-grit sandpaper or a Scotchbrite pad and wipe down the brake rotor earlier than bedding within the new pads. This removes the previous pad materials and lets the brand new pads chunk onto the disc. 

As for the outcomes – nicely, let’s simply say it reinforces what we are saying quite a bit right here at MO: brake pads can remodel a mediocre brake setup. The preliminary chunk is straight away stronger than the inventory pads, which is a giant grievance with the delicate commonplace pads. And because of that sturdy preliminary chunk, the general braking energy feels extra sturdy, too. The more durable I pull the lever, the extra keen the bike is to decelerate. If I have been to nitpick, I’d say the Brembo grasp cylinder is now the weak hyperlink, as there appears like a tiny little bit of play within the lever, completely different from air within the strains. However total, this improve is an absolute should for any MT proprietor, for my part. If in case you have the usual MT-10 and never the SP, I’d counsel altering the pads first, then changing the rubber strains for metal.

Whereas they have been at it, EBC despatched an unsolicited pair of its XC contour totally floating brake rotors which can be a direct alternative for the stockers. These run roughly $250 per facet or about $500 for a pair such as you want on the MT-10. The totally floating choice is sweet, and so they do weigh just a few grams lower than the inventory discs. Set up, too, is very easy. Simply unscrew the previous and exchange it with the brand new (don’t overlook the thread locker!)

In contrast to the brake pads, nonetheless, the distinction with the XC discs wasn’t as noticeable over inventory. Positive, the totally floating function is sweet as a result of it ensures fixed and constant contact with the brake pads even because the temperature rises, however in actuality, I’d have been hard-pressed to inform the distinction. So, as good as EBC was to ship this with the set of pads, on the subject of bang for the buck, I’d decide to spend the cash elsewhere. 

Leo Vince Cat-Delete Midpipe

If retaining your bike 100% road-legal is of utmost significance to you, then cease studying this part now. 

For the remainder of you, the Leo Vince cat-delete midpipe (and others prefer it) is an affordable and easy improve that not solely frees up some energy and awakens a rumbling (however delicate) growl from the engine, but it surely additionally sheds over 13 lbs from the underside of the bike. I prefer it as a result of it additionally allows you to maintain the inventory silencer, so that you’re not compelled to spend extra cash to purchase a slip-on exhaust if you happen to don’t wish to. To not point out, retaining the inventory silencer retains the sleeper look and a modest exhaust be aware at idle. 

Set up of the midpipe is straightforward – it’s eradicating the inventory midpipe/cat that’s a little bit of a course of. There are a sequence of bolts to loosen or take away, a few of which reveal brackets which can be primarily to assist the heft of the inventory cat. Most of those bolts and brackets received’t be reused. You additionally have to loosen the O2 sensors and place them out of the way in which (extra on that in a minute). Eradicating the inventory silencer offers you house to slip the inventory cat off the exhaust headers. After that comes elimination of the push/pull cables used for the Yamaha EXUP valve, because the valves and the cables received’t be wanted anymore. This requires loosening the strain on the EXUP valve itself earlier than eradicating the cable, then you possibly can have the required slack on the servo motor situated beneath the seat to undo the cabling up there. 



Now, as for the servo motor itself; at this level, you possibly can disconnect and take away it and save somewhat little bit of weight, however as Nate Phipps, the ECU flashing wizard at 2 Wheel DynoWorks knowledgeable me, “the ECU desires to see voltage from each emissions system, regardless in the event that they’re practical or not, to ensure that cruise management to work.” Since this bike remains to be ridden on the road, and never completely on the observe, cruise management is vital, and I saved the servo motor linked and in place.

As for the O2 sensors, these additionally aren’t wanted anymore, and the Leo Vince midpipe has plugs you possibly can screw into the bungs to cap them off. Nevertheless, I made a decision to maintain them in place for a few causes. First, eradicating them meant tracing the wires again beneath the gasoline tank, which implies lifting or eradicating the tank. Frankly, I didn’t really feel like taking the tank off. However second, and extra importantly, eradicating them would disable cruise management for all the identical causes as it will with the EXUP valve. So, they stayed.

With every thing free and cables gone, some wiggling and muscle slides the cat proper off. Putting in the Leo Vince midpipe couldn’t be simpler, particularly as all of the {hardware} is offered. You place the hose clamps in place, slide it onto the exhaust header, line the assist tab within the center with the present bracket on the bike, place the inventory silencer again on, line up all of the bolt holes, and bolt every thing again collectively. Executed. As for impressions, it’s greatest to save lots of that for the ultimate improve…

ECU Flash

Tying this entire factor collectively is the ECU flash carried out by the aforementioned Nate Phipps at 2 Wheel DynoWorks. Earlier I known as him a wizard, and that’s as a result of he actually is on the subject of this ECU flashing enterprise. He is aware of these Yamaha ECUs in and out. By his personal depend, he’s flashed over 100 FZ/MT-10 ECUS by the years. Evidently, he was an amazing information for this venture. 

Truly, Phipps flashed the ECU twice. The primary time was when the bike was 100% inventory, together with the manufacturing unit catalytic converter. Even in inventory trim, there’s efficiency available, and Phipps discovered it. In case you’re curious, right here’s what certainly one of his ECU flashes entails: 

• Customized IAP Gasoline Maps (Particular to your exhaust system)
• Customized TPS Gasoline Maps (Particular to your exhaust system)
• Customized Ignition Timing Maps
• Customized Digital Throttle Valve (ETV) Maps
• Adjusted Fan Temperature
• Disabled Evap / Purge Valve Fault Code
• Disabled Inventory O2 Sensor Fault
• Disabled Deceleration Gasoline Lower
• Disabled EXUP Fault Code
• Disabled PAIR Valve / AIS Fault Code (Aftermarket exhaust solely)
• Disabled High Velocity Limiter
• Customized Engine Braking Management Maps

As well as, once I rode the MT-10 SP on the observe in inventory type, I discussed how the autoblip downshifts have been very exhausting to have interaction, requiring me to house them out farther than I wished. I suspected this was Yamaha’s manner of saving the engine from over-revving and Phipps confirmed it when he talked about “there’s a 250-rpm buffer constructed into the ECU to forestall the bike from exceeding the rev limiter when downshifting. The sort of buffer is definitely current in each ECU/bike that comes with an autoblipper from the manufacturing unit. It’s merely there to forestall engine injury.” When he adopted up with, “We are able to definitely improve the rev limiter very safely by 500 rpm, which ought to massively ease this challenge!” I clearly bought my hopes up.

Just like altering jets on a carburetor to have an effect on efficiency, a flash can change the EFI gasoline mapping to get the air/gasoline ratio the place it needs to be. That’s a comparatively easy factor to meter for on a dyno. The true magic with ECU flashing comes right down to ignition timing, and as Phipps revealed to me, “for this particular ECU I needed to advance and retard the timing in locations.” Precisely the place, and the way a lot he both went excessive or low, is the key sauce most tuners maintain near their chest. 

Changing the cat with the midpipe meant there was now extra air being launched to the engine. If left alone the bike would have been operating lean. So, the ECU was despatched again for one more flash so as to add extra gasoline and convey the AFR again in line. As for the outcomes, check out the dyno graphs beneath.

Earlier than moving into the outcomes, we first want to determine that these numbers seem like low. A number of sources have instructed me that even a inventory MT-10 needs to be within the low 130 horses on the rear wheel and stand up to 150-ish horses after the mods. I’m not precisely positive why these numbers are studying low aside from operator error (me), although I put my very own private bike on the identical dyno and it appeared abnormally low, too. Possibly we’re coping with a extremely stingy dyno.  

Nonetheless, if a single horsepower and torque quantity are all you’re on the lookout for, you’re partially lacking the purpose. Let’s have a look at the general graphs, beginning with the inventory MT-10. The lull within the midrange is noticeable each on the road and the observe, although we are inclined to ignore it as a result of it nonetheless pulls nicely sufficient. Have a look at each the horsepower and torque curves with only a flash and we are able to see the dip flattens out considerably over inventory – a distinction that’s very a lot noticeable, as second-gear roll-on wheelies are mainly the norm now.

Transfer to the midpipe and flash, and despite the fact that the horsepower curve is marginally higher than simply the flash within the midrange, have a look at the torque curve and the midrange distinction is large in comparison with simply the flash and big in comparison with the inventory bike. That is, indubitably, one thing you possibly can really feel from the saddle. 

The opposite large distinction comes on the finish of the graph. You may clearly see the inventory bike signing off round 9500 rpm earlier than hitting its rev restrict round 11,000 rpm. After the flash it’s clear as day to see the elevated rev restrict Phipps opened up, and with that comes one other large achieve in energy and torque. Personally, I’m not placing a lot weight on the minor variations in peak energy and torque. I’m a lot happier with the general graphs, to not point out the tremendous easy throttle response.

On the road and on observe, these variations are abundantly clear. Round city, there’s speedy energy to overhaul others and be even lazier with shifts, whereas on the racetrack the additional midrange and prime finish bursts you out of sluggish corners and reveals what the bike can do on the straights. Equally as good is the uncorked sound the crossplane crank makes as you twist the wrist. The delicate growl at idle transforms to a raucous bark as soon as the bike will get all riled up. It’s music to the ears. 

Negatives

This isn’t to say the expertise has been all roses and sunshine, although (but it surely largely has). There have been some negatives up to now. First, elevating the rev restrict did nothing to resolve the sluggish and clunky autoblip downshifting. I’m led to imagine it’s simply the way in which it really works and the shift sensor isn’t as refined as others. Within the meantime, I’ve resorted to utilizing the clutch if I have to bang off some fast downshifts. It’s disappointing contemplating that’s the entire level of an autoblipper.

Possibly the true adverse right here is the quantity of fuel this bike drinks now after the ECU flash. Extra air from the midpipe means extra gasoline, and over the course of eight classes (which is each single one) at Auto Membership Speedway with Fastrack Riders, I blew by my spare 5-gallon gasoline jug and needed to beg and borrow about two or three extra gallons to complete the day. That’s by no means occurred to me earlier than. As of press time, I’m nonetheless working by a full tank on the road, however after about 100 miles, the gasoline gauge is exhibiting somewhat greater than 1 / 4 full. 

General First Impressions

Downshifts and gasoline consumption apart, I’m extraordinarily proud of the MT-10 SP up to now. These three easy mods – brake pads ($80), midpipe ($290), and ECU flash ($350) – have solely set us again $720, however have fully reworked the bike (don’t depend the brake discs since they’re not mandatory). On the road, it’s a docile commuter if you need it to be (thanks, cruise management!), however is prepared at a second’s discover for the weekend canyon blast. Then it will possibly additionally pull double responsibility and shock folks at a trackday, too. The facility is wholesome sufficient to maintain an ear-to-ear grin in your face, the crossplane crankshaft sound will maintain you coming again for extra, and the usual traction/wheelie/slide controls will defend you from your self if you happen to get somewhat too trigger-happy.

Additionally spectacular is the Öhlins digital suspension. I’ve purposely solely fiddled with the automated settings (and never the guide settings) to see how it will react to completely different street and observe circumstances, and easy button presses make a distinction – normally for the higher. The one hiccup I’ve observed is extraordinarily bumpy roads could make the suspension lag because it figures out one of the simplest ways to manage.

All that’s left to do now’s to proceed to place miles on the bike to see if the honeymoon section lasts or if there’s a chink within the armor that’s but to be uncovered. I’d nonetheless wish to put a bigger windscreen on it, however world provide points have made one more durable to return by than I anticipated. And if this thirst actually is dramatic, that might doubtlessly be a disadvantage, too. Who is aware of. Possibly it’s time to see if this bike may give its Euro counterparts a run for his or her cash.
