Mate after two years as so far changed nothing, But initially he was commenting on a few things on the bike, i remember he thought the exhaust silencers were a bit off putting, the chrome but painted end section, and the plastic guards and plastic y chrome look indicator bodies. There was talk of him swapping the bits he did not like, But it seems over time, with him using the bike in all weathers as a commute tool quite often, i think the Plastic guards at least have if anything gained his respect even though not perhaps quite to his tastes in a retro bike.
Rear shocks? I only rode the bike that one time, but it was a long ride and on variable roads and i thought the stock gabriel rear shocks were ok in function i am a similar weight to the owner and i left his settings well alone. I sent the bike on in the turns and the Rear shocks were i felt for a factory offering and given the bikes price point were if anything more than adequate and certainly not bad IMHO. But i do get the Suspensio upgrade deal, and i am as sure as i can be that a person could change shocks etc and even improve a lap time perhaps, but my thoughts are at least try it thourhgly first, cam it up a bit see how it functions for you how you ride what you do and of course Your own expectations and requirements. It might well be you simply must have the changes, but it could go the other way. Just saying ,, and of course its your bike your needs and YOMV.
