Racing Crankshaft DRT for

Vespa PK50/S/SS/XL/XL2/FL/HP/N
/Rush
disc valve, stroke 45,0mm, conrod 87,0mm,
cone 20/20mm, M12

FOR RACE USE ONLY

Denis Innocente from DRT Racing is well known for his gearing and special clutch parts. For Smallframe Crankshafts, he's specialized in long stroke crankshafts for short strokers. This is especially important for those wanting the max out of their motors without going over 125 cc's.

 

The Race and Full Circle Crankshafts are enlarged with an exenter stud from 43 mm stroke up to 45 mm. This increase in stroke enlarges a 102cc engine up to 107cc and a 112cc engine up to 117 cc. Lots of torque, improved acceleration and more power in all rpm ranges are yours here. The motor characteristics are close to an original ET3 and it’s really fun to ride.

 

Helpful hint: All cylinders - except D.R. 50-102 cc's and POLINI 115 cc's - need a 1 mm base gasket to balance out the increase in stroke.

 

Conclusion: Elegant and hefty tuning part for smaller class motors.

 

Racing or Full Circle Crankshaft / 45 mm stroke / 87 mm connecting rod / 19/20 mm, M10/ 20/20 mm, M12 

Racing / full circle crankshaft with ø 82 mm crankweb (flywheel side), Ø 87mm crankweb (disc valve side), excenter stud with 45 mm stroke, 87 mm, oil seal housing 19/20 mm, bearing housing 20mm, pointed cone with M10 thread or stump cone with M12 thread, includes connecting rod bearing.

 

SIP-TIP: new bearings, crankshaft gasket rings and woodruff key are a must, new gaskets, clutch and flywheel nut also. Don't forget to order a 1.00 mm base gasket.
