To be honest, the way Yamaha price up their parts, there is little chance of an insurance company not writing the bike off these days if you were to have a very minor accident.
Even a rear wheel for instance is priced as new at £688.49on the AJ Sutton site, yet you can pick one up on Ebay for £25+, and it'll even be round too.
Does kind of change your ways of thinking about insurance policies, 'cos no matter what you personally value your bike at, you're gonna get mugged off if push comes to shove.
