Crankshaft Naraku racing +2mm

For technology-inspired tuning freaks we offer this reinforced GY6 Racing crank with a 2mm longer stroke. This is a no-frills product. 4-stroke pro’s will know what this is. When you run out of bore, stroke is the only option. So if 180cc isn’t enough, then you can get stuck in with this crank. The compression and longer stroke should be evened out with thicker or doubled-up gaskets. As opposed to the usual 4 or 6mm long stroke cranks available on the market, these do not require a longer timing chain.
