The Ultimate Crank for your Yamaha YXZ 1000R. Available in stock stroke 66.2mm or as stroker cranks at 71mm.
WARNING - These crankshafts do not come balanced, ready to install. You will need to balance for operation. Add $200 per crank for TPR precision balance, bobweights required if using own piston and/or rod combo. 4340 billet crankshafts in stock stroke (66.2mm). MUST USE WITH SIDEWINDER OIL PUMP/SPROCKET. All cranks are stress relieved, shot peened, Magna flux inspected, and nitride (multi-step heat treatment) for ultimate performance. Fully profiled counterweights are designed for reduced windage through the crankcase creating less oil resistance for better rpm potential. These cranks must be fully system balanced prior to installation due to various bobweights.
