RDM Reinforced Stroker Crankshaft
Choose any stroke!
Rdm takes China crankshafts, modifies them to have 10mm of press fit length per side just like my hyper race billet cranks, the process also allows me to change the stroke!
90mm rods so these will raise the piston 1mm, you may need to add another gasket to correct. Rods are perfect quality CKR kits custom made in Taiwan for our engines.
12mm silver plated needle bearings up top, 10mm needle bearings are available upon special requests.
These are the new standard for built 66/80cc bicycle motors a must have.
Send in any brand new 66/80cc crankshaft as a core and receive $20 gift card to the store that can be used for any purchase!
cranks come pre balanced and straightened ready for 47-50mm pistons.
