Tyga 300cc big bore kits

This is a simple bolt on replacement top end kit which radically improves the power characteristics of your NSR250. It transforms the mid range, allowing for much greater acceleration out of turns. But that's not all, there is power everywhere! The peak power is noticeably improved and consequently top speed and the engine feels stronger all over. This is the biggest boost you can give to the performance of your NSR250. Why simply rebuild your engine when you can upgrade it with one of these kits? Why wait until you need a rebuild? Take the 250cc top end off and save it in a cupboard and bolt this 300cc kit on and enjoy the difference!

(Please note that due to cylinder differences, the standard NSR expansion chambers will not fit without modification, and this kit does not include expansion chambers)

Due to the extra power of the 300cc kit, it is essential that your base engine is in good condition. This applies particularly to the crankshaft and clutch assemblies.
These are also available from us Dry clutch rebuild kit and Bottom end rebuild kit
