Jcosta variator it634fs pro burgman 400 2007-2012

Used for only 600 km.

- Improvement in:

o Smoother performance.

o Better aerodynamics.

o Weight reduction (inertial control).

o Higher refrigeration allowing less temperature due to the new variator design with sink.

o Higher quality for all components of speed control, higher durability and less maintenance.

- We get:

o Faster operation.

o Higher reaction on the throttle Press-Depress of the rollers.

o Reduction of the fuel consumption.

The new PRO speed control series, differs from version before by taking a heatsinks within the speed control in a circle provided with projections, between rollers area and bushing area. The rollers cavities are holed for the Press-Depress effect making them to act more quickly and smoothly both at the entrance to a higher gear as the output of a lower gear showing no jumps, it makes the air as fluid dynamic to help the rollers to emerge or be collected faster without increasing fuel consumption.
