You’re not allowed to remove any material though (except for drilling it to fix fairing brackets and stuff). But on a Superbike you can beef things up with tubes and gussets.

It’s worth pointing out that you can’t use aftermarket electronic suspension (if you want to use electronic stuff, you can only use the OEM gear).įrame-wise, you can’t touch anything on a stocker, and you have to run the standard sub-frame. They also use bespoke superbike swing arms, that offer extra strength where they need it and extra flex where they need that. The Superbike boys can, and do, run completely different, beefed up forks as well as running aftermarket shockers. But you’ve got to keep the standard fork outers. You can also change the internals of the forks by slotting in an aftermarket cartridge kit. In a stocker, you can change the rear shock for a complete aftermarket unit, be it Öhlins, Maxton, or whatever. This is where the Superbike teams can really go to town. That means you can use any pipe you like in either class as long as it’s no louder than 107dB. Aftermarket clutches can be used in a superbike, as well as bigger (or additional) radiators and you can modify the oil pump.Įxhaust choice is free in Superbike and Superstock. You can change the con-rods, but their weight must be the same or greater than the original homologated parts, and they have to be the same length. Cam sprockets or gears can be changed so you can tilt the cams to adjust the cam timing, and cam duration and lift are free. Porting and polishing is allowed and you can set the compression ratio to whatever you feel like. In a Superstock bike, just about everything else has to be standard too (with the exception of the base gasket).īut there are a few bits you can do to a Superbike engine to get a bit more power. And in both classes, you can’t do a massive amount to the standard engines crankshafts, pistons, cylinders and valves have all got to remain standard.

Yes, Superbike and Superstock engines are both 1000cc (or 1200 if it’s a twin). But these days, particularly in BSB, it’s not the case. You might think the engine is where the biggest differences are, and once upon a time, you might have been right.

If you’ve ever wondered what £30k will get you, compared to £100k+ in the BSB paddock, wonder no more as we ask, BSB Superbike vs Superstock… what’s the difference? Engine To the naked eye, and from a dozen or so paces away, a Superbike and a Superstock bike might look the same.
