Racing full-cheek crankshaft from Malossi for geared mopeds with Derbi D50B0 engines. RHQ stands for Racing High Quality and it`s true to its name. The crankshaft is stable up to 16.000 RPM. Malossi uses only the highest quality nickel / chromium / molybdenum steel for durability. The full-cheek design allows a significantly higher pre-compression and therefore the best possible fill rate at higher speeds. The flow-optimised surface treatment prevents performance reducing turbulence in the crank cases. Not the cheapest crankshaft in the range, but certainly one of the best from the tuning specialists Malossi.
