I think Rizoma do adapters that do fit. I'm suspecting the price may be as bad if not worse than Ducati though. Still mulling aroundI've ordered a set with no obligation to buy and been told mid - end May delivery in the UK. Personally prefer Ducati stuff with connectors fitted etc but at £250.00 for 4 I'm considering all other options. In the past I've bought ShinYo Arizonas, always very pleased with the quality but you'll have to source adapters or cut the wires, maybe Rizoma adapters will fit ?
