I am running pilots on mine - fast road & track - they work a treat. The rear is a 160 profile - so it is designed to work with low bhp bikes, like the 400's, super moto's etc

No problem & not invalidating the insurance

ive got the nc23 but im running bt 014 r's and m8 the grip is wicked id go with them for sure!!!!!! cant wait untill the 016's come in 18 inch sizes thou!!

You can babble tyres til the end of the earth, simple end of it is this:
commuter: BT45
often used for fun at w/e: BT92
only used at the w/e: BT090

Get them from Russ in Portsmouth, he's the only guy worth talking tyres to. Barely dearer than the www, and he'll fit them for you and sort you a cup of coffee while he does.

anyone noticed how tyre prices have been going UP latley?
last yr a rear cost me £80 fitted. this yr its over £100 for the same tyre!

excellent reponses all, even though I commute got the bt092's all fitted for £190

will see how i get on with them, how long should they last ? I don't ride hard

i commute and the BT090 rear has only lasted a year from new.. i am going for 092 rear and i expect it to last longer.

On the subject of speed ratings. For insurance AND safety purposes. You can go UP, but not DOWN.
I sell/fit tyres for a Job.

I'm running Pirelli supercorsa in a Z rating. Took them out today, They warmed up pretty quickly and stuck to the road like sh!t to a blanket.

At the moment i'm using BT014 (ZR rating - 160 rear) but the next time i want to have some Pilot Powers.

And yes - in germany you can use ZR tires on 400 bikes.

1 whole year??

You must babyfoot around on that thing.

did you miss the "i commute" bit?
every single day, in all weathers....... no car or car licence. bike only, been like that for over 9yrs now.

the centre is squared off and has no tread left. plenty round the edges! had shite weather last summer to do corners right, then winter, had a few good days so far this yr.
i do a lot of duel carriageway/Main A roads to/from work + do occasional deliveries.
BT090 rear is NOT ideal for how i ride, i prefer BT092s on rear and 090 front.
