Fitment and Purchase Checks

Yamaha 40X Enduro family from 1998, including 40XMH, 40XW, 40XWT, 40XWH and E40X. Also fits the Parsun and Hidea T40 copies built on the same design. Not the older C40 from the eighties, check the serial prefix with us first.

Why This Unit

Enduro engines run in the worst conditions there are, silt, heat, salt, overload. The starter takes it all. Copper windings, coated armature, sealed case. Fit a water separator in the fuel, a flooded cylinder hydrolocks and bends the pinion.

For Buyers and Distributors

Warranty covers six months. 20 pieces minimum order, 10 to 15 days to ship. Dealers keep two or three on the shelf for the season rush.
