This model is the BRK 4 RACE for FOR RACE, for racing, cut in the best steels, it has a reinforced polished finish rod which rests on an increased crank pin, anti-friction wedges with silver cage to support the highest speeds .
Attention, stroke version 40.7mm increased + 1.7mm. Allows the increase in displacement, diagrams and compression ratio, to be installed with a shim or a seal of around 0.8mm in addition to the base base seal !!
Unlike the competition model (just below), this vilo has a real work on the lubrication but also on the balancing and real full masses, it therefore offers a performance gain and a real reinforcement of the low engine. It will be perfect to accompany 50cc or 70cc medium and high power kits.
This vilo with its weight has excellent inertia and a very good finish with a nice aesthetic. Delivered with its needle cage Ø12mm X Ø16mm X L.16mm. This version in bristles (bearing seats) with a diameter of Ø17mm is to be mounted with bearings of the original size reinforced Ø17mm X Ø40mm X L.14mm. An unbeatable value for money!
