To the naked eye, and from a dozen or so paces away, a Superbike and a Superstock bike might look the same. But they?re not. 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

You might think the engine is where the biggest differences are, and once upon a time, you might have been right. But these days, particularly in BSB, it?s not the case. Yes, Superbike and Superstock engines are both 1000cc (or 1200 if it?s a twin). 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. In a Superstock bike, just about everything else has to be standard too (with the exception of the base gasket).
But there are a few bits you can do to a Superbike engine to get a bit more power. Porting and polishing is allowed and you can set the compression ratio to whatever you feel like. 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. 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. Aftermarket clutches can be used in a superbike, as well as bigger (or additional) radiators and you can modify the oil pump.
