Race Tech Suspension

[andcad]

Hi Guys
Has anyone installed Race Tech HI-Performance Springs in their front shocks. I did this in my gen 1 and it made a big difference to the handling of the bike. I think by memory they put in .95kg springs.
I weigh at the moment 95-96kg (and loosing, trying to get down to 90kg) and I think the bike is about 240kg (has a Yoshi 4 into 1).I was going to put in 1.1kg springs, just a little concerned that they may be a little to heavy.
Any advice would be appreciated

Cheers

No good just doing the springs. u need it revalved also. @ 90 kgs and loosing the spring rate should be ok.

Yes doing the valves aswell

Don't forget the rear that's if you haven't already done it because it's no good just having the front done either.

I got RaceTech front springs in my Gen2. The rate 1.2kg/mm. I weigh 88 kg and they are just right. 0.95 seems a bit low for Busa with 90 kg rider. What is your rider sag?
As Kawasuki said without re-valving you will not gain much from the springs alone other than having your forks working range right.

Shifu , Did you get the forks done at Hoeys or elsewhere ? Looking at mine $600 front total, Springs/gold valves/ seals etc . Reasonable ?

Yeap, Peter did the springs change over and the valves. Price looks very much the same. He is not a rip-of artist. He will adjust the sag for you as well if you ask. I did the gixxer myself (after making a spring compression tool) saving about $200 in the process, but only because I wanted to build the shim stacks myself.

Thanks Andrew , yeah sounded reasonable to me & he knows his shit .

If u want someone to do a pro job and have a chat before u buy
ring Krooz Tune in Vic his name is Dave U can send the forks there he will do one of the best jobs u could imagine he will also explain about your rear shock and how it will need to be done in a proper fashion. This shop did last years Ozzy super bike winner and this year he will also be doing the Honder Super bike team as well, but u must mention my name
Easyrider Imports and dont worry there is no commission.

Hi Shifu,
The recommended spring rate for me on their web site is 1.059 at rider 90kg and bike 240kg. As i am still 96kg I was thinking at going the 1.1kg spring, and I was only guessing the weight of my gen 2 with the Yoshi 4 into 1 exhaust system. Yes I will be re-valving as well, just a bit concerned 1.1kg may be too heavy.

Please remember that the normal setup for the road is rather soft. The extra 0.1 kg will not make as much difference but it will allow you some firmer setup without maxing the compression and a margin for drop in rate over time. I got 1.1 kg/mm springs in my Gixxer that weights only 180 kg and can still get from them 35mm sag for riding on our bumpy roads.
