Derbi Variant Start 5 C.40 Crankshaft, 80 Connecting Rod, RB Racing

Crankshaft C.40 80 connecting rod RB Racing for Derbi Variant Start 5.

If you are looking to get the most out of your Derbi Variant Start 5's engine, there is no doubt that you need to reinforce the crankshaft, providing the necessary strength to withstand high-displacement setups.

This is not a conventional component. This model features a 40 stroke and is equipped with a high-precision machined 80 mm connecting rod that withstands thermal and mechanical stress at high revs. Its 72.5 mm outer-diameter webs and its weight of 1330 grams are designed to balance inertial forces, which significantly reduces destructive vibrations in the crankcase and will provide greater stability in the crankshaft. With this technical balancing, the engine pulls with more power and delivers an immediate response when accelerating.
