Description

Doppler Endurance Crankshafts for highly tuned scooters

Doppler Endurance is the strongest crankshafts in the Doppler range and is designed for scooters with highly tuned engines that demand more than a standard crank can handle. The Crankshafts are full round, which means it increases the primary compression in the engine and therefore the overall power output. It’s balanced up to 18,000 rpm, so it can handle even high-performance tuning setups without compromising durability. The heavy-duty INA bottom bearing ensures the Crankshafts are solid and long-lasting, even under heavy loads. Comes incl. 10x14x13mm Needle Bearings.

Fits Yamaha and Aprilia with Minarelli vertical engine

This version of the Doppler Endurance Crankshafts is intended for scooters with Minarelli vertical engine, including Yamaha BWS/Spy, Yamaha Slider 50, Aprilia SR 50 and Aprilia Amico 50. It fits ø10mm crosspin, so be sure to check this before purchase so the Crankshafts match your cylinder kit and Pistons. Note that there is an equivalent model for the Minarelli horizontal engine, so choose the right version for your scooter.
