Welcome. I have thought about a Thunderbird. 6 gears. Belt drive. But the weight savings is minimal, and the trade offs seem too great. Now with 13,000 miles the R3 is "home". I almost
never ride it without it just making me happy. And she is brilliant 2 up. I've just put on a Bridgetown 240/55 Exedra Max and it is, in my opinion, a better handling bike. Enjoy the rush!
