BIDALOT / Ref. 330 00 351
This gearbox, Evolution 2021, can be fitted to all DERBI Senda Euro1, Euro2, Euro3 engines as well as DERBI GPR engines.
Made in the best steels, with high breaking load and elastic limit, all pinions were resized, and we made changes to the dental corrections to improve the strength of the teeth.
These boxes allow the power of the high-displacement Racing Pack to be passed without obstacles.
You will notice that this gearbox is delivered complete, ready to install, the primary and secondary shafts being delivered assembled with all washers, seals and other needle bearings.
All these elements are original DERBI references.
You will find in the link below, grouped in a tabular way, the new stages of each gear, compared to the original box.
- Z1 = Number of teeth on each primary pinion
- Z2 = Number of teeth on each secondary pinion
- Z1 / Z2 = Gear ratio of each gear
- The percentage of maximum speed in each gear compared to maximum speed in 6th gear
- The percentage difference between each relationship
- The speed to which the engine drops when shifting from a gear above 14,000 rpm
