I havent checked the sprockets to see how many teeth they have so I'll do that this weekend.
Our open road speed limit in New Zealand is 100kph and this is policed pretty strictly, so Im not really looking for huge top speed. I do hear what you're saying about the high first gear so I'll have to give the whole thing a real think through.
On a slightly linked topic does fitting a 19" front make the speedo more accurate? mine is well on it's way to being 20% over.
Have a great day
