A couple of weeks ago, i invested in a flywheel locking tool from Moto rapido Ducati. Approx £110.
Some on ebay are 2/3 the price. It’s an updated design to the genuine tool i borrowed a few years ago. I had to borrow one at the time, because the ‘ Laser tools ‘one i had bought was sh@t!
Just don’t make the same frustrating mistake!
You’ll need some threebond or a gasket from exact uk.
