Product description

DRT reacts to the recent developments that POLINI have produced with their racing cylinder kits and so satisfies all fans of the 135cc racing class with their 53mm stroke crankshaft.

 

This longstroke crankshaft, has the stump ETS cone with the 20/ 25mm oil seal and bearing housing diameters. The full circle web halve flywheel side has an outer diameter of 85mm. The 53mm stroke that this crankshaft provides combined with a cylinder bore of 57mm results in the 135cc that the Italian racing class requires. The highly polished con rod (length 105mm) surpasses the POLINI crankshaft in efficiency and also ensures a more effective pre combustion and more performance in all areas. Lubricating slots provide the best lubrication for the big end bearing of the connecting rod.

 

Conclusion: Excellent production quality combined with the best value-for-money in its price class.

 

Longstroke crankshaft/ stroke 53mm / connecting rod 97/105mm / 24/25mm, M12

Longstroke crankshaft with flywheel side crankweb halve (Ø 85mm), balanced, sturdy 105mm connecting rod, oil seal housing 24mm, bearing housing 25mm, stump cone profile with 12mm thread, incl. connecting rod bearing

 

SIP-TIP: Originally designed for the POLINI EVO reed valve cylinder, this crankshaft goes also well with MALOSSI, FALC, QUATTRINI or PARMAKIT cylinders. Do not forget to order the flywheel side bearing and -oil seal.
