Correct Pressures

Im using 0.88kgmm springs and They recommended 0.9kgmm for my weight so im not so far out it should matter.

So would me putting a longer spacer in fix the slight issue?

The values aren't massively different though, unlike the CB.

Standard values, as I understand it, are 29/33, but Bridgestone say it should be 36/40 on BT-45, which is a great deal higher.

Are they quoting for two up riding? Or does the different tyre really need such a drastic increase in pressure?

I always ran 36/42 with Z6s on my SV1000, both solo & with a pillion, without any problems - 29/33 are waaaay too low for the road.

Completely unknowingly I ran my Conti Road Attacks at 22/30. Bike felt great and I did some of my fastest riding at those pressures. As soon as I realised how low they were I slowly increased them first to 28/34 which felt rubbish, felt like the front end was slipping constantly and then to 32/36 which was were I stopped as I lost the front end and crashed and my bike set on fire.

My point is tyre pressures are completely personal for you and the bike your on. I believe my bike suited a low pressure on the front due to having very, very hard suspension. It had a tendancy to jump off the ground over a sucession of bumps and the tyre needed to flex to stay in contact with the road. I pumped up the tyre, I get less flex and less contact and bang no bike. Obviously the problem here wasn't tyre pressures it was the suspension that was cocked up but the tyre pressures made it work.

The difference in spring you're talking about is negligible and shouldn't make any difference. 20 grams per kg isn't going to be noticeable.

You can add your own spacers in the form of washers. Head down to your local engineering shop and get some that fit inside your forks. I'm running 5 washers each side in the hornet.

Here's a tutorial I did for the Hornet forum. Works the same for the SV forks (did it to the curvy too) and should be possible with the falco...

Check the washers fit into the fork legs by lowering one in on a piece of wire. make sure they aren't too tight as they'll strip your form caps.

Sorry for diverting the thread!

Nooooo, 29/33 for the CB500 (and the NSR as it happens). Sorry I wasn't so clear on that. I run 36/36 on the SV. I'll try experimenting a little, I want to have a play with the suspension too. I feel comfortable on 36/36, but then I haven't messed around with them so maybe I'll have a play this weekend.
