Rim widening from 3.0" x 17" up to 12.5" x 18"
We widen the original cast wheels of your motorcycle! The advantage is that you can then drive wider or even changed in diameter wheels / tires without having to make further changes to the bike. The wheel hubs remain unchanged, only the rim beds are changed. Of course you have to take into account the clearance wheel-chain, wheel-cardan, wheel-belt and the width of the swingarm.
In most cases, the original rim widening for motorcycles is also the most cost-efficient way to realize wheel size changes. For widening, the original rim beds are turned on special lathes and then machine-welded to corresponding larger rim beds using the TIG welding process. The weld is no longer visible in the outer area of the rim beds and the rim looks like a "normal" rim. A strength certificate with identification is enclosed.
Note: If you are unsure whether your rim can be widened, send us a picture by mail in advance! We will be happy to advise you. Here's why: Cast rims, which have a rim bed, into which no cast spokes run from the inner star, can generally be widened (that's most rims). However, there are also rims where the cast spokes merge into the rim bed. Here, it is usually difficult or even impossible to widen the wheel.
Furthermore, the following applies: A rim can be widened by a maximum of 2.0" in the same diameter, e.g. 3.5" x 17" to a maximum of 5.5" x 17". Wider is also possible, but then the diameter of the rim must be increased by 1", e.g. 5.5" x 17" to 10.0" x 18".
The wheels are blasted before processing and must be resurfaced after widening, which we of course also offer - just select the desired variant (coated, painted, polished).
Our variants here in the store are always based on delivered 17" or 18" wheels. Other dimensions on request by mail. Please send or deliver wheels without attachments (brake discs, tires, sprocket carrier) by mail to us.
