Bolt on race power for the RGV250 VJ22 and RS250.
Proven to boost power accross the range to give a very good increase with no porting or conventional tuning. Careful set up of the squish and cleaning of the ports can release more potential as can adjusting the ignition. The curve below shows results with standard map included in the Zeeltronic box to show a fair starting point to your tuning.
To fit this kit TTW assumes that you already have a set of quality pipes such as Lomas, Jolly Moto, Arrow etc as it has not been tested with Standard pipes which can be restrictive.
TTW assumes your engine is in a fresh condition, there is little point bolting premium parts to a tired engine. A top end rebuild is recommended every 6000 miles.
The below example shows what can be achieved very easily.
