Thinking of putting a different front end on my nc30 is this a worthwhile mod or is it better to upgrade forks with new springs etc? What forks would be best and how easy is it to do if I did go down that route also is the 17 inch rear wheel the way to go for rubber choice? Is the nc35 a straight swop?

First of many questions appreciate any advise thanks

The guy I bought mine off fitted zxr upside down forks and gsxr 6pot calipers with rc30 discs, said it wasn't massively difficult.

Performance or looks??

The standard forks can be made to perform just about as good as anything out there and don't cost a whole lot to upgrade.

If it's better looks you want then you can't argue with a nice shiny upside down front end with radial brakes.

RVF 17" rear wheel is a straight swap. Still some good rubber available for the 18" rear, but options will only get more limited in the future. Try a search regarding specific tyre info.
