Increasing ground clearance

[Steve6088]

I'm having ground clearance problems. I have fitted cbr900 forks to the front of my bike and this seems to make the bottom of the bike sit much lower. This is particularly apparent on track where I get the bellypan and sometimes the downpipes grinding the floor.

Would increasing the preload or fitting stiffer springs increase ground clearance? I intend on getting it all set up properly by someone before I do another track day.

This photo shows how little clearance there is, even with only a moderate lean angle.

Weighted springs will help as you ain't small or light ya big fooker .

I have weighted springs in my blade forks and I get some very impressive lean angles and haven't grounded out .
Having the bike weighted to you kitted up will make a ton of difference just make sure you use linear springs

Me, I would have just asked what are your sag settings?

Though I do agree getting the suspension set up is step 1 to making the bike work.....
Big HP and Massive Brakes mean nothing if the tires are not touching the ground.

Hanging off might help, too.

Marquez seems to have a bit of an idea about that; he basically falls of to the inside but keeps hold of the bike and lets gravity shove him back on it as he gets near the corner exit.
I'm told that a 1kg/m spring helps, apparently some Kawasaki 1000's come with these springs.
For myself I'll be looking at K Tech or Hyperpro springs, if I had more money I'd be after cart's too, but for now that'll have to do.

Are your clip-ons mounted above or below the tripleclamp? The CBR forks are shorter and, to maintain ride height, require that the clip-ons be mounted beneath the upper clamp.......

I've tried increasing the amount of preload on the forks to try and reduce the amount of sag on the front forks. I've got a measurement somewhere. How much sag should I be aiming for with the forks, with me sitting on the bike?

I've got the clip ons mounted under the top yoke, as they should.

I think Santa is bringing me a set of fork springs for christmas? What brand would be best? Just any which arnt progressive?

You could fit 19 inch wheels

Failing that, try pumping up the tyres a lot more

The other option is to sell the forks to me
