Sorry – not a Scott topic – but a question that I’m sure some of you learned people will be able to help out with.
I have a Honda 600 RR which I try and thrash around circuits when time / finances permit (but also take it out from time to time for a pootle out on the roads). It’s pretty much stock and I love it from the point of view of handling etc.
But, increasingly, I find that I get held up by the 900’s / 1000’s going into the corners only to be out accelerated (though not by much) on the exits.
It’s also pretty clear that I tend generally to only use 2nd / 3rd / 4th or 3rd / 4th / 5th depending on the track and that speed wise I’m only getting to something like 120 / 130. Standard gearing gives a book top speed of approx 160mph.
So – my thought was, change the sprockets to lower the gearing, which would allow me to keep the nimble handling and give me a better chance of matching the larger machine’s acceleration on exits.
However, I have simply no idea of of what impact any change in tooth numbers would make. Currently it has a 16T front sprocket and a 42T rear sprocket.
Anybody got any ideas of what a “first stab” would be?
– if possible do not use a front sprocket smaller than 15 T as this puts a lot of strain on the outgoing axle and chain.
– make sure to choose such a combination of chain length and number of teeth on the front an rear sprocket that will not have the chain running over the same teeth everytime. If you know what I mean.
A first step would be to fit a 15 T front sprocket. This would shorten the final drive with about 6 percent and you can probably still use the same chain without having to shorten it (you can probably put the rear wheel a little more to the rear). This mod really made a feelable difference to my Yamaha SRX. And a front sprocket only is about 10-15 GBP so worth a shot.
