NC30 F3-TT, SS and SP

[jb1000rr]

Can someone explain to me what the history and differences between the F3-TT, HRC SS and the HRC SP versions of the NC30 are?

F3 is your Japanese racing series

SS = Supersport

SP= Sports production

NC30s are all the same though - you need various kits to upgrade them to the specs for the different kits.

As far as I am aware you could look at them like this:

F3 is like WSB

SS is like Supersport in WSB

SP is like Super stock in WSB

Think they had different tuning regs with F3 being the furthest away from the road bike that was available to buy

Thanks for the replies.

So each of the three NC30 classes (F3-TT, SS & SP) could only use certain NC30 HRC kits or parts. I've only got the HRC manual for the SS & SP, it seems that the only difference between these two classes was the front wheel? What additional HRC parts were available for the top of the class the F3-TT? And presumably all these different HRC kits that were available would have fitted the NC30 regardless?

The TTF3 manual can be found at the front of the site here:

As you will see the TTF3 manual has many more parts than the SP manual, The F3 spec bike would be in a much higher state of tune than the SP bikes

Some of the SP parts come up for sale occasionally but the F3 stuff is very very rare

Thank you for the link, you've been really helpful and knowledgeable,

The parts list may only show the front wheel is different but if we could read Japanese it could very well say the SS class wasn't aloud any from of tuning, the SP class may be tuned with porting, skimming heads etc
