I Ride: 2007 V-Star 1300, 2014 ZX-6R, 1986 Yamaha YZ250 (bored & stroked - 2 stroke)
So I have a 2014 636. I know all racing circuits/organizations are different, but when I'm watching the Supersport races, my favorite, like in WSBK, MotoAmerica, BSB, Isle of Man and even CMRA, etc... Am I rooting for my 2013+ 636 or am I rooting for a 2012 599cc or homogenized special 2018 or 2019 599cc? I know it's legal in atleast some racing circuits, but what makes it legal as I know they put restrictions on the Triumph 675 & 636. One of them is a minimum weight & possibly fuel tank size?

And IF I ever race, it would be at the lowest Amatuer levels unless things drastically changed in my life, would I be able to race my 2014 636 ABS? I've put ALOT of money into it, about $7500-$8000, and have plans on doing some engine work...

Like installing my Kawasaki Racing .50" Thin Head Gasket (thinking about buying a .45" instead,) Port & Polishing my heads, $1000 Camshaft Regrind by WebCam which requires High Performance Valve Springs, Lifters & High Compression Pistons (haven't asked thrm if a Thin Head Gasket can substitute for the unavailable HC Pistons yet,) E-85 Conversion (haven't figured out what's all needed & where to get it from, yet) and even though I know this isn't race legal, a compact Water-Meth Injection System.
Everytime I think about the total cost of what all of this takes and add it to how much I've invested already, I remind myself I need to stop or I'll never get my $25k 2020 Aprilia RSV4 1100 Factory (in addition to, not in place of my ZX6R)

So I just want to know if the reason why the ZX6R I'm seeing on TV is getting passed in the top end on the straights or digging in & pulling away on corner exit is because of that strong low & mid-range 636 motor...

2014 ZX-6R 636: M4 Street Slayer Exhaust, FlashTune Bike Tuning Kit, Bazzaz Z-Fi, Z-AFM, MJS Headers, K&N Race Air Filter, RaceTech Gold Valve Fork Kit w/ Bottom & Top-Out Mod, reshimmed & RT Fork Springs, RaceTech Gold Valve Shock w/ Refreshed internals & RT Powdercoated Lime Green Spring, D.I.D Gold Chain, Vortex -1 front sprocket, PMP Sprockets Anodized Green +2 rear aluminum sprocket (-1/+2), GPVR4, Fender Eliminator Kit, MotoDynamics Smoked Integrated LED Taillight, '13 Lower Green Fairings, R6 Throttle Tube, Pro Grip Padded Tank Pad, Stomp Grip Clear Tank Pads, Pazzo IFX Candy Green Shorty Levers, Raskal Graffiks Wheel Decals, Puig Double Bubble Dark Smoke Windscreen, Driven Block-Off Plates, Driven Gold Spools, Morimoto Mini H1 7.0 Bi-Xenon Projectors, Morimoto 5Five 50w 6000k HID's, (6) Morimoto XC RGB Angel Eyes, Pirelli Diablo Rosso Corsa's, etc...

The 636 is legal to run in Motoamerica with no restrictions. It is also legal in every club in the US. I believe World Supersport still uses the 2012 bike as that is what the rules allow.

As far as club racing goes. At my local club, Their are classes within each weight class of bike. Supersport, superbike, and grand prix.

In the supersport class you can change internal parts in the forks, the rear shock, and add basic bolt on parts to the engine (exhaust, air filter, fuel controller, etc.). This is the class of bike almost everyone has (or says they have) so that they can run as many races as possible. This is the lowest spec of bike so if you have a supersport bike you can ride it in the superbike and grand prix races which are different races run at different times.

If your bike has any kind of engine work done to it, it is now in the superbike class. If you change the wheels to anything other than oem ZX6, its a superbike. If you change the swingarm, its a superbike. If you change the injectors, its a superbike. You get the idea?

Grand prix is basically the same thing as superbike, except their are literally almost no rules. If you had a moto 2 bike, this is the class you would run it in. Supersport and superbike are for bikes that were once sold as road legal machines to the public.

Class structures are different for most clubs. If you are serious about wanting to race, which I would highly recommend doing because it is fun as shit, lookup your local clubs rulebook and start reading.

woohoo we are having fun now
Stupid people say stupid things on the internet, so be wary of who those people are. If you solicit advice on the internet, just keep in mind 99% of what you'll receive is not based on fact or science-and likely atleast 95% of it is based on bullshit and bravado regurgitated from some other schlub who also did not experience any of what they claim and are also full of shit. If you don't like my bluntness- too bad. I am not here to please you, so move along, your approval is not desired nor is it needed. So before opening your pie hole and adding more stupidity, perhaps sit back, listen, absorb and learn something. You know that saying, it is better to remain silent and thought a fool than to open your mouth and remove all doubt!

Your 2014 ZX-6R is plenty fast in stock form. It is even faster with just race rubber. It is faster still with a properly tuned suspension. Until you are at the limits of the machine with those two simple mods ...... you are probably the bottle neck, not the bike.


It is your money, and you can do with it what you want, but you should be better served by spending it on 1) fees to actually get on the track (track day, practice, race, etc.), 2) tires, and 3) suspension.


Money can be spent all kinds of different ways that do not make you faster. A few examples are paint jobs, shiny things, carbon things, engine mods, exhaust pipes.


I highly suggest getting on the track ....... road racing is still THE MOST EXCITING thing that I have done so far in life.

I agree with the guys above. First off regarding classes, I believe WSS is the only one that doesn't allow the 636 and they still use the previous gen. Here in the US, the 636 can compete with no restrictions from the factory. If you've never raced before, let alone done a bunch of track days, don't even touch the engine. Let it be as it is and spend your money on track days, race fees, tires, brakes, suspensions, etc. Engine should be last, when you're an expert racer and fighting for podiums in said expert races.

I see you're in Enid, OK...which means your home track is Hallett. That is not even much of a power track, it's short and technical. CMRA guys are fast there, with top 600s running 1:16-1:17s. Until you can break 1:19s there, you shouldn't even consider engine mods. Most guys that do track days there and run in the advance group can't even get in the low 1:20s (myself included back when I lived in that area, although I was slower than now). As a comparison, Rocco Landers, the 14-year old who won the Junior Cup this year ran a 1:20.0 on his 400 there!! Which is insanely fast and proves you don't need much power to go fast around there.
