Apart from all the usual stuff like binning the number plate hanger and rear indicators, the main improvements are the ABM handlebar conversion to take the wrist pressure away. A booster plug, to allow the bike to run better, and a louder exhaust silencer to get you heard in traffic. The crash bars should also save the radiator and engine cases in a slow slide or fall.
Everything else is really only cosmetic to make the bike a little bit different.
Pretty much everything came from eBay apart from the handlebar conversion. I don’t think I want to add anything else at the moment.
