SPEEDOHEALER V4 Healtech Yamaha 1 (SH-V4+SH-Y01)

The Speedohealer V4 is a small electronic box to correct the speed displayed on your machine counter. The use of this accessory is common after a change in the transmission ratio (number of different teeth on the crown and/or the box output sprocket compared to the origin).

You thus visualize your actual speed and no longer distort your total trip: a less tooth on a PSB distorts the speed of 5 to 7%!

In addition to a change in transmission ratio, this accessory can also be used after a modification of tyres (different dimensions of origin) or simply to correct the factory deviation (a counter is always voluntarily increased by a few per cent).

The maximum speed reached is recorded and can be displayed on request.
