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

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

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

4 key points why the VOCA HQ crankshaft!

1. Unlike common 43 mm stroke crankshafts with 84 mm connecting rod, the Voca crankshaft comes with an 85 mm connecting rod that will strike first in the timing of common 54 mm cylinders.
2. Connecting rod with optimized upper diameter to allow the use of 12x17x16 mm needle bearings for use with 12 mm pistons and 14x17x17 mm for use with 14 mm pistons.
3. Faces enlarged to 77 mm instead of the original 75 mm to increase pre-compression in the crankcase without the need to machine the crankcase.
4. Perfectly counterbalanced with aluminum (upper) and bronze (lower) inserts for use with heavier 54 mm pistons and to optimize maximum rotation.

Strength is guaranteed and it is capable of reaching up to 16,000 RPM.

Characteristics:

• Stroke 43mm
• Connecting rod 85mm with 12x17 x16mm bearing
• Upper black aluminum inserts and lower copper inserts for perfect counterweight for 54 mm piston
• Crankshaft faces of 77 mm. Maximum diameter to increase crankcase pre-compression, without the need for machining.

Attention! You must carry out balancing checks before installing in the engine, since manufacturers deny warranty for any balancing fault found after installation.
