1997 CBR900RR (T or V) K-Tech Fork Air Gap????

Hi All.
First post here as given the name of the site I am hoping for your help.
I have a 1997 CBR900RR & am about to fit some 9.0 K-Tech Springs.

Now, K-Tech say 115mm air gap & the separate suspension company (was several quid cheaper?) I bought them off says 130mm air gap???

Im guessing the spring itself has more volume that the stock spring so I would assume a larger air gap than the book says is needed!? Book says 114 (+- 4mm)

To my untrained head the gap of 130 is sounding more like it but read all number of different gaps around the web!?

Please help if you can as it would be much appreciated.

All the best, Steve

Hi Steve, welcome to the best Fireblade site on the web (but only if you have a 92-99 )

I put Racetech 1.0kg springs in my 93 and 99 for some track riding and a fat ass rider (aka 200lbs). In both instances it called for a fluid height of 120mm.

It sounds like K-Tech has their own number on their springs. I can't see a 4kg spring being necessary unless you're 400Lbs (which could be, not judging )

But I agree that such a spring would need to be quite thick and displace more fluid that a 1kg spring.

I set both my 900's at the 120 mark with no complaints.
