„There is only one way to make up for lacking displacement – add more displacement" – tuning parts manufacturer KÜBLER Racing from Bonn has adopted this motto and offers conversion kits for the LEADER 125cc and 200cc engines.
These kits feature a converted crankshaft and include among other things a complete cylinder kit, a new camshaft drive chain as well as all bits and pieces that are necessary for the conversion. This conversion is not a simple plug&play task. You will need to cut away a part of the oil baffle plate! Additionally, you will need the flywheel of the LEADER 200cc engine for a conversion of the 125cc engine as well as the 125cc primary fixed sheave for the conversion of the 200cc engine! The increase in both torque and performance (approx 20hp) make this conversion definitely worth its price!
