I bough pretty expensive ones (recommented by Wild Goose Moto Guzzi forum) to my Moto Guzzi Neveda. Maybe something which HD riders might use? Add the shipping cost from USA to Europe (not cheap). Lastly the the custom costs/taxes here. Perhaps because of original high total costs I even went to buy/add one extra part to them later (in the middle of them ,,,, see the red marked parts) to get them really installed into the right position. Luckily those did not cost much anymore. (Ebay) Over all those peds are now longer and even more flexible (how you can turn them) than originally. Still I did not succee on that. Guzzi's cyliders (type of their V2 engine) mainly caused that. Also, the crush bar of Nevada's engine (shape of it) made it challanger.
BUT I did not put those away either with Guzzi as I changed it to my Tiger 800. So who knows, I might tested them one day again.
