Sergio said: My main concern is how it will handle with the bigger wheels (16" -> 17") and the lowered forks. The bike should have a weight of about 110kg/ 242lb and I'm about 85kg/ 187lb. Click to expand...

The change from 16" to 17" wheels isn't a big one, but enough to go from twitchy and a tad unstable (for some) to more stable but still quite agile. The biggest difference would be if you were swapping a 16" front for a 17", but I'm guessing its the rear that is going so it will make a difference but not a huge one.The cast alloy wheels may well be strong, but they sure aren't light, especially once you load them up with a disc and a tyre. You may want to think about keeping the stock wire wheels, unless of couse they are rusted and buggered. They have the bonus of being light and will look schmick once you polish them up.As for tyre availability, I can still get tyres for my '84 Suzuki and that runs a 16" front wheel and 18" rear. 17" is the common size for most modern bikes and almost universal for sports bikes made after 1990. I would not worry about availability of tyres for 17" wheels - you'll have your pick of anything from $400 trackday specials to $90 runabouts.Cheers - boingk
