Here is the BIDALOT Racing Replica crankshaft for DERBI euro 3 and 4 engine (latest generation also mounted on 50cc APRILIA, DERBI, GILERA motorcycles). It is one of the best crankshafts on the market! It may well be much cheaper than MALOSSI MHR for example, it remains very efficient, studied and solid. It has an ultra studied and dynamic balancing (proven by its blue mallets).
The inertia is excellent. The masses are obviously full for more pre-compression, they are also case-hardened and specially treated (which gives this burnished color). It is directly taken from the real competition crankshaft BIDALOT Racing competition. The connecting rod is a reinforced model, it rests on an increased crank pin reinforced between 2 anti-friction shims, a small end cage also increased for less friction and well reinforced. The lubrication is reviewed, this vilo is designed for a Ø12X16X16mm cage or even Ø12X16X desired length!
It comes with its needle cage. The finish is really perfect ... Certainly the best quality / price ratio on the market, this crankshaft will offer you performance, strength, well attenuated vibrations ... The bristles are in original diameter therefore Ø20mm. This crankshaft will support without any difficulties all the most powerful kits like the BIDALOT RACING REPLICA 50 or 70cc, the MALOSSI MHR Team…. You will have to assemble it with the original balancer because this crankshaft is made for.
