Re: Where to buy in UK
The first rule of thumb is to buy from a reputable seller. Too many of the ebay kits are sold by people with no motor bike experience and are only in it for the money. You'll want good after sale support and a means for communication to the seller. Check the advertisers listed down both sides of this page. They all have good reputations and can be trusted. A little research on your part will benefit you.
