The famous STAGE 6 BIGRACING special for 45mm stroke, power and torque galore for a reduced price on your DERBI euro 1 & 2 engine motorcycles.
The BigRacing cylinder range presents itself as extremely high-performance cylinders from the brand with the 2 stars. Considered hyper racing, they nevertheless offer a very interesting performance and reliability ratio for regular and intensive use, even daily.
Made of aluminium, with a displacement of 88cc (with the appropriate 45mm stroke crankshaft), this range of kits is mainly intended for 50cc motorcycles with Derbi Euro 2 engines (before 2006)
Combined with a modified exhaust system, full intake and transmission, maximum power, torque and top speed are significantly increased!
To find even more performance from Stage6, you will have to turn to the R/T range, which is more radical and clearly intended for use on the circuit.
