XS1200 Engine Short Block

Part No: SB_XS1200

Product Description:
The XS1200 engine is breaking all the power barriers for pro riders who demand the best. Our XS1200 made its competition debut at the 2011 World Finals in a new Dominator version of our Kong Hull (KDX). This engine uses an 84mm billet crankshaft designed, built and balanced specifically for the XS1200 (Stroke 84mm x Bore 94.5mm/95mm). The engine features modified Yamaha 66E cases with a custom stator plate allowing the use of a Yamaha 701 / 62T style MSD Total Loss ignition system. No exhaust adapter is required for 701/760 style exhaust systems. The short block includes custom bedplates and a billet front cover.
