there is no instructions but mine fitted ok Do the right hand side first by taking out the long bolt that goes though the frame The nut size on the left hand side is 17mm You do not have to put a jack under the motor as there is other bolts that hold the motor to the frame
That is correct The crash bars for sale at the moment only fit 2020/2023 Triumph Rocket 3 GT but new crash bars for your model wont be long before they are on the market
When i know more i will keep in touch
Kind Regards
