High quality casted alloy cylinder kit with an ultra hard wearing Nicasil coating. The EVOLUTION gives more than enough port areas and very vivid port timings to get a real powerful scooter. The exhaust port is divided by a bridge and the kit has a 6-port transfer system.
The idea behind the EVO cylinder kit is that it is a complete tuning range that gives amazing results when all parts are fitted together. High End racing engines have to be built with using the best parts available. Otherwise they will fall apart sooner or later! The exhaust stub is different so you have to use the EVO exhaust anyway.
A well setted up EVO engine makes a show winner out of every nerd. Wheelies at 80 km/h are unbeatable in terms of the coolness factor.
A 24 mm carb is the minimum required. So you have a 22 hp engines at 13.600 rpm and has an over-rev potential to more than 15.000 rpm.
