CIGÜEÑAL VOCA HQ RACING 43MM/85MM YAMAHA DT LC/D
Thanks to its experience in preparations Voca Racing offers us its HQ Racing Standard Races range.
Made from high quality materials, offset with aluminum bats to reduce weight and increase performance. This cigüeñal offers the strength needed for high-end preparations, in addition to its closed design that ensures greater precompression in the cárter.
Equipped with CNC machined crank with logo engraved with láser.
¡4 key points of whyé the cigüeñal VOCA HQ!
- Unlike common 43mm stroke 43mm cranks with 84mm connecting rod, the Voca cigüeñal comes with an 85mm connecting rod that hits first on common 54mm cylinder strokes.
- Connecting rod with optimized upper diameter to allow the application of 12x17x16 mm needle roller bearings for use with 12 mm pistons and 14x17x17 mm for use with 14 mm pistons.
- Faces enlarged to 77 mm instead of the original 75 mm to increase precompression in the cárter without the need to grind the cárter.
- Perfectly counterbalanced with aluminum (upper) and bronze (lower) inserts for the use of heavier 54 mm pistons and to optimize maximum rotation.
The resistance is assured and it is capable of reaching up to 16,000 RPM.
