Some Triumph and Ducati models have single sided swing arm(often shorted = SSSA). Ducati have many models of SSSA wheels. Also lot of special wheels and cheap used wheels are available for Ducati that are not available for Triumph. So I found this yellow Ducati wheel for 60euros, so can I fit it to Triumph?
The fitment is similar in both. The tabs that hold the wheel in place are the same diameter and size, but the offset of the wheel is different. Ducati wheel center is 15mm lower compared to the Triumph. So 15mm spacer is needed to fit Ducati wheel to Triumph. And that spacer needs to hold the triumph hub tabs and have new tabs that hold the Ducati wheel from not spinning.
Also the outer spacer needs to be made. Triumph normal spacer doesn’t work for Ducati wheel.
Friend of mine made these spacer for me(inner and outer) and it has worked great. I usually keep the touring tyre on the Ducati rim and some more track worthy tyre on the original Triumph wheel.
There is no real weight benefit, because this style Ducati wheel is at least same weight as Triumph wheel. But with this spacer I can use almost any Ducati wheel on Triumph.
