Crankshaft Voca HQ Racing 43mm/85mm Yamaha DT LC/D

VOCA HQ Racing Crankshaft 43mm Stroke 85mm Connecting Rod for Yamaha DT LC/D

Thanks to its experience in preparations Voca Racing offers us its HQ Racing Standard Races range.
Made of high quality materials, offset with aluminum bats to reduce weight and increase performance. This crankshaft offers the necessary strength for high-end preparations, in addition to its closed design that ensures increased pre-compression in the crankcase.
Equipped with CNC mechanized connecting rod with laser engraved logo.

4 key points why the VOCA HQ crankshaft!

1. Unlike common 43mm stroke crankshafts with 84mm connecting rod, the Voca crankshaft comes with an 85mm connecting rod that will hit first in the times of common 54mm cylinders.
2. Connecting rod with top diameter optimized to allow the application of 12x17x16mm needle bearings for use with 12mm pistons and 14x17x17mm for use with 14mm pistons.
3. Faces enlarged to 77mm instead of the original 75mm to increase crankcase precompression without the need for crankcase grinding.
4. Perfectly counterbalanced with aluminum (top) and bronze (bottom) inserts for the use of heavier 54mm pistons and to optimize maximum rotation.

Resistance is assured and is capable of reaching up to 16,000 RPM.
