1 x High Speed Variator Set for 139QMA/QMB engines
Component No: NK900-20
Colour : Standard

The Naraku High Speed Variator is considered one of the best variator’s on the market for the 139QMA/QMB engines. The variator comes pre-supplied with matching rollers weights that are suitable for use on all setups, however 63cc on up receive the best performance improvement. The variator is 10% lighter than standard variator and comes supplied with larger more robust sliders. Also in the kit is a shorter drive boss (the perfect length for these scooters) and a set of high performance rollers(5.8).

The 5.8mm rollers are suitable for 50 - 72cc kits . As always variator tuning is in coordination with engine tuning and these roller weights may not give the best improvement if you have carried out further tuning work.
