As it happens, I have a towbar for sale!
A towbar? Will it pull a caravan?
Lol. I want it fitted to a Fazer.
Well, mine was designed to bolt straight on to a FZS600, no mod required, apart from adding a plug to your loom. So yes, it will tie a caravan, provided it's a small one!
Under UK law, you are allowed to tow a trailer no longer than 2m from your rear axle, 1m wide, nor exceeding 2/3rds of a Fazer's wet weight. As if they'd ever check that last one!
Search the forum for the thread "Trailer trash" for more info / piccies.
