Consumer culture. READ the warranty. Ride it the year, THEN mod it. Piaggio would be nuts to warranty bikes that such wankers have twaddled with. It's part of growing up, junior....
Wouldn't an '03 have the 43mm hollow axle forks and better discs?
audiomick, Were it mine, it would be worth a couple of letters or some internet sleuthing to contact the owners, for some PEACE of mind.
Lacking a crash, the later forks/brakes are actually a decent upgrade. Any way to trace ownership back and speak with the prior owners? That name or names might be in any paperwork which came with the bike.
