My NC30 is running and handling well. Wondering what (if anything) to do to it next?

Cosmetically and mechanically it's good and it's got:

Slip-on can and jetted to suit
+2 rear sprocket
Ignitech CDI with HRC map
RO earth upgrade kit
Goodridge hose all round
Steering damper

Light Wheels!

Getting a new (or rebuilt) shock is a wise upgrade especially if your current shock is as saggy as a pentioners ball bag.
Front forks often need a bit of attention after years of abuse.
If your after more ponies they're hard to come by without spending big bucks.
How big is your wallet?

ACU licence.... come racing on it

600RR rear shock

Some good suggestions, thanks. Some BT090s are first on the list come the spring I think!

How about Maxton shock and forks.

Ohlins shock and KAis Fork Upgrade, Braking Disc and CBR600 calipers.

An hrc sticker or two?

RC30?
