Personally I really like the Motortrike Rocket III. That will be the one I get when it is necessary. It can actually be purchased through Triumph new with all the warranties.
Well, just had this fitted to front wheel, £70 new not bad me thinks, bridgestone 160/70/17, rear tyre fitted wrong way round, looks real good on the wheel.
1 thing, I think I'd want a drivers back rest on a trike. Seeing as your not really moving around in the seat anymore, it would make sense to make "lounge chair" comfortable
I am biulding it to go to rallies camping and all that. pulling a trailer. the wife was finding it difficult to jump on the bike when all packed up. carn't get her old legs over everthing etc.
But not to worry just in process of buying this. So not all is lost. 2013 bike 440 miles on the clock and only 10 months old.
cheers.
PS, sorry about the picture size. don't know what that's all about. basically mat black with white stripes.
