OK, will go with the 150. Although the gradient of a 150/60 should technically be the same as a 160/60, as the profile is stated as a percentage of the width.. So the profile of a 150/60 is 60% of 150mm and the profile of a 160/60 is 60% of 160mm.. Which means the ratio of width:profile is the same, right? (Or maybe it's because I'm not considering that the rim size stays consistant..)

Anyways, someone commented the other day that the bike dropped a fair bit when I sat on it (and I'm only 70kg)..

I haven't played around with the suspension at all.. How hard is it to fit a shim on the rear shock, and how much is the shim worth (and where can you get it)?

Cheers guys. Helpful as usual! :D

EDIT: Is this the rear shock shim you speak of? http://cgi.ebay.co.uk/HONDA-RVF400-NC35 ... 663wt_1137

Being an RVF (17" rear wheel) you have a lot more tyre options than VFR's (18" rear).

BT014's might be a good compromise for you, still a very grippy tyre and you'll get more life out of it than an 090. Also, not really up to date with them but a michelin pilot sport (or whatever their newest middle of the road sports tyre is) will also be pretty good on the rvf.

Go for a 150 rear, your slow turn in will be due to the tyre size and also because as standard these bikes sit a bit too low in the rear (you can raise it with a shim on the rear shock - improves it big time).

You will only get a few thousand km's out of the bt090's and alpha 10's (which are pretty much treaded race rubber), but I reckon it's a waste to fit long lasting tyres to an NC - grip and handling are what these bikes are about. At the end of the day, it depends on your mileage, budget and the type of riding you do. These tyres have saved my life on the road at least once at last count...

Grip is king! 8-)

I'm with Cammo on the above, i can get some very nice lean angles on my bike with the Bt090's fitted and i haven't had a single twitchy moment from the front or back end at low or high speeds. I tend to hold back on straight line blasts, if i do i will try and roll the tyre a little if blasting down a straight (3 lanes every where where i live) As mentioned the fun is in the corners and these 090's provide it by the bucket load, if you are commuting or a straight line speed junky (no disrespect intended) :) then the only other tyre i would presonally go for would be the dual compound 092 :)

Just my 2p :)

The side-walls are Higher though.

90mm vs 96mm for the 160... this is what makes the difference, slightly more flex and due to the narrower rim the tyre shape is slightly different too.

I'm assuming that is yes, that is the shim for the rear shock..

How hard is it to install the shim? (Never touched my shock before..)

Are there any other things I should do to improve my suspension without spending too much?

Cheers :grin:

Easy ;) it just lives above the top shock mount - simple when you are looking at it.. 8-)

Trackdays.... :whistle:

hmm so stick the bike on the rear stand, unscrew the shock (but not all the way up I'm guessing), slide the shim under there and tighten it back up?

Do I need to support the frame, or is this only if you're removing the whole shock?

And in response to your track day suggestion, I'm still just learning to ride, but I am planning on doing a California Superbike School course at the end of the year, and then beginning of next year I'll do a couple track days if all goes to plan! Can't wait! :D

You'll need to take the weight off the rear end, so a rear stand won't cut it. You can rig up a car jack under the rear headers, abba stand or similar. Just be thankful that it's easy (and cheap!) to add ride height on an NC35 vs an NC30!

Great plan! The more track time the better 8-)

See you on the track!

On the issue of 090 versus the 003rs, when I fitted a 003 front and still used a 090 rear, I all the sudden got loads of rear end slides, where as I really never had any with 090 front and rear... So good is the 003 compared to the 090, but given price and intendend use they should be.
