These engine mount bushes are made here in the uk by ourselves at Classic Bike Fasteners.
The metal insert is cnc machined in one piece made to be long lasting and will never break, unlike the original Suzuki/aftermarket (cheaper made) item that was two parts tacked together and often broke apart after a few years of use.
They are exactly the same size, shape and dimensions as the original bushes made by Suzuki which are now discontinued.
