Again within the ’70s, Cycle journal coined the time period “Common Japanese Bike” to consult with the proliferation of normal bikes constructed by the Japanese Huge 4 that adhered to the identical method: air‑cooled inline‑Fours with tubular cradle frames, disc entrance brakes, telescopic forks, and twin rear shocks.
A lot has modified within the final 5 many years, however producers nonetheless follow tried‑and‑true formulation when designing bikes. Today, no matter the place bikes hail from, there was a convergence within the middleweight class on parallel‑Twin engines as a result of they’re price‑efficient to provide, simple to package deal inside a body, and versatile when it comes to tuning. Also referred to as vertical Twins as a result of the 2 facet‑by‑facet cylinders stand upright, trendy variations sometimes have liquid cooling, gasoline injection, and a 270‑diploma crankshaft that produces a V‑Twin‑like rumble.
Final 12 months, Suzuki, a veteran of the UJM wars, launched a liquid‑cooled 776cc parallel‑Twin that powered two new fashions: the GSX‑8S bare sportbike and V‑Strom 800DE journey bike. The engine has DOHC, 4 valves per cylinder, a 270‑diploma crank, throttle‑by‑wire, and Suzuki’s patented Cross Balancer system, which minimizes vibration. The GSX‑8S is supplied with a number of Suzuki Clever Experience System digital rider aids, together with throttle response modes (Energetic, Fundamental, and Consolation), multi‑mode traction management (1, 2, 3, and Off), an up/down quickshifter, Straightforward Begin, and Low RPM Help.
Commercial
Chinese language producer CFMOTO entered the U.S. bike market in 2022 and has expanded its lineup to 11 fashions for 2024. Considered one of its latest is the 800NK, a unadorned sportbike powered by a liquid‑cooled 799cc parallel‑Twin that’s a earlier‑gen model of the KTM 790 engine, which CFMOTO now builds underneath a partnership settlement. Much like Suzuki’s modular strategy, the identical engine is present in CFMOTO’s Ibex 800 journey bikes. On the tech entrance, the 800NK has throttle‑by‑wire, throttle response modes (Sport, Avenue, and Rain), and cruise management however no traction management or quickshifter.
These in search of an reasonably priced, streetfighter‑styled bike would seemingly cross‑store these two bikes, particularly since there’s only a $500 delta between their MSRPs: $8,999 for the Suzuki and $8,499 for the CFMOTO. To suss out their variations, we examined them again‑to‑again on native freeways and backroads and had our good friend John Ethell at Jett Tuning run them on a Dynojet dynamometer.
CFMOTO 800NK vs. Suzuki GSX8S: Marvel Twin Powers, Activate!
Regardless of only a 23cc distinction in displacement between the CFMOTO and Suzuki, there’s a big distinction in engine output. Each Twins rev out to just about 10,000 rpm, and their dyno curves present pretty linear will increase in energy and flat torque curves. Previous 6,000 rpm, their curves start to diverge, with the CFMOTO climbing to 93.4 hp at 9,400 rpm whereas the Suzuki ranges out at 75.9 hp at 8,300 rpm. Torque figures are nearer, however the 800NK nonetheless has the benefit within the higher rev vary, maxing out at 57.1 lb‑ft at 6,600 rpm in comparison with 53.3 lb‑ft at 6,700 rpm on the GSX‑8S.
The CFMOTO additionally has a decrease curb weight, giving it a better energy‑to‑weight ratio. It weighs 410 lb with its 4.0‑gallon tank full, whereas the Suzuki weighs 445 lb with 3.7 gallons in its tank.
Variations in energy and weight aren’t readily obvious at decrease rpm and round‑city speeds, however the Suzuki feels extra refined. The GSX‑8S begins simply when chilly, idles easily, and has spot‑on fueling and throttle response. The 800NK, alternatively, is sluggish to heat up, idles prefer it’s in a nasty temper, and reveals some hesitation when making throttle changes between 4,000 to six,000 rpm, which corresponds to a dip within the horsepower and torque curves.
Above 6,000 rpm, nonetheless, the CFMOTO finds its groove, responding cleanly and on to throttle inputs and making its energy and weight benefits readily obvious. It flicks backwards and forwards by means of tight corners extra simply than the Suzuki, and a twist of the wrist catapults the 800NK forward extra quickly than the GSX‑8S, which falls flat within the higher rev vary. Though sound doesn’t essentially have an effect on efficiency, it does faucet into our feelings. The CFMOTO’s extra aggressive exhaust notice makes for a extra participating driving expertise with out being too loud.
GEAR UP
There’s additionally some daylight between these bikes when it comes to shifting. Each are geared up with 6‑pace transmissions with cable‑actuated slip/help clutches. Neither bike requires a lot effort to vary gears, however the Suzuki’s gearbox is noticeably smoother, and it’s aided by the comfort of a quickshifter. The CFMOTO has an adjustable clutch lever, however the Suzuki doesn’t.

Extra Bounce to the Ounce
When producers purpose for aggressive value targets, one of the vital frequent locations to chop prices is with the suspension, notably when it comes to adjustability. Each CFMOTO and Suzuki sourced their elements from Japanese suspension maker KYB, and each bikes have inverted forks (43mm on the CFMOTO, 41mm on the Suzuki) and rear monoshocks. The one adjustability on the GSX‑8S is rear preload, however the 800NK gives full adjustability on the fork and rebound and preload adjustability on the shock. Experience high quality between the 2 is pretty related, with their damping charges calibrated for normal use reasonably than the tautness of extra aggressive sportbikes, however the CFMOTO permits riders to dial of their preferences entrance and rear.
The CFMOTO has a slight edge when it comes to braking. With elements sourced from J.Juan, a Spanish subsidiary of Brembo, the 800NK has a pair of 4‑piston radial entrance calipers pinching 320mm discs, a 2‑piston rear caliper pinching a 260mm disc, a radial‑pump entrance grasp cylinder, and metal‑braided strains. The 800NK’s brakes present sturdy, constant energy with good suggestions from the adjustable entrance lever, however they may use extra preliminary chew.
The Suzuki wears Nissin brakes, with twin 4‑piston radial entrance calipers squeezing 310mm discs, a 1‑piston rear caliper squeezing a 240mm disc, an axial‑pump entrance grasp cylinder, and rubber strains. Stopping energy is respectable, however the Suzuki’s brakes really feel extra numb and supply much less suggestions than the CFMOTO’s. ABS is customary on each bikes.
GEAR UP
Sit Up and Be Someone
The 800NK and GSX‑8S are compact machines with brief wheelbases, slim waistlines, and sporty chassis geometry. Each have metal frames, metal subframes, solid‑aluminum swingarms, and tapered aluminum handlebars. From the cockpit, the Suzuki nearly disappears beneath the rider due to its svelte tank, 1.7-inch narrower handlebar, and slender (however 0.4 inch taller) seat. The CFMOTO’s tank and bodywork flare out extra, and its handlebar is wider, giving it extra visible presence from the saddle. Its seat can also be wider on the again and has thicker, extra comfy foam.
As streetfighters, these bikes lend themselves to an aggressive driving model, however they’re comfy sufficient for on a regular basis driving or commuting. Their handlebars’ bends and risers enable for an upright seating place, and their footpegs are positioned excessive sufficient for good cornering clearance however low sufficient for satisfactory legroom.
If you exit the freeway and discover your option to a winding backroad, they’re more than pleased to show their athleticism. Each roll on 17‑inch solid wheels with 120/70 entrance and 180/55 rear tire sizes, and their radials – Maxxis Supermaxx ST on the CFMOTO, Dunlop Roadsmart 2 on the Suzuki – present impartial dealing with and respectable grip. With its further steering leverage and 35‑lb weight benefit, the CFMOTO is extra agile than the Suzuki however not by a lot.

CFMOTO 800NK vs. Suzuki GSX8S: Satan within the Particulars
In some methods, these are two evenly matched bikes, whereas in others, they diverge. One is constructed by a effectively‑established Japanese model that has been constructing bikes for the reason that early Nineteen Fifties and promoting them in America since 1963. The opposite is constructed by an upstart Chinese language firm that has been constructing bikes solely since 2000 however has grown quickly and never solely builds its personal engines and bikes but additionally builds them for KTM, Europe’s largest producer.
Though the Suzuki GSX‑8S was launched in 2023 as a brand new mannequin with a brand new engine, it feels very refined. It has the construct high quality and match and end one expects from one of many Huge 4 Japanese producers, and its engine, electronics, and chassis work collectively harmoniously. The GSX‑8S prices $500 greater than the 800NK, but it surely has customary options that the CFMOTO lacks, similar to traction management and an up/down quickshifter. Its vibrant TFT instrument panel makes use of a bigger, thicker font and is simpler to learn in all circumstances than the one on the 800NK.
As the brand new child on the block seeking to construct belief out there, CFMOTO’s worth proposition is to supply extra bang for the buck. For the 800NK, that begins with the tried‑and‑true KTM 790 engine that delivers a further 17.5 hp and three.8 lb‑ft of torque over the GSX‑8S motor. It continues with a 35‑lb decrease curb weight, suspension with extra adjustability, larger‑spec brakes, and options like cruise management and smartphone connectivity. Not solely is the bottom value decrease, but it surely comes with a further 12 months of guarantee protection. Nevertheless it additionally feels rougher across the edges, notably concerning its low‑rpm fueling.
Should you’re an skilled rider who desires a lightweight, highly effective, considerably rowdy streetfighter and may reside with out traction management and a quickshifter, you’ll need the CFMOTO 800NK. However for those who’re somebody who prioritizes smoothness and refinement over energy, or for those who’re a more moderen rider, the Suzuki GSX‑8S is for you.
