Raise the front of 94 CBR900RR; can't find bar risers

I just got a nice deal on a '94 CBR900RR. My complaint if very minor - on low speed corners steering is a little too quick but on anything fast it's on rails. The previous owner had Lindemann Engineering rework the forks. I'm unable to locate any bar risers and am considering lowering the fork tubes to decrease my angle to the bars for more comfort. If anyone has some bar risers please let me know they seem to be out of stock and out of production for this model excepting a set for $380 I found. I figure the steering might slow a little with this change and that wouldn't bother me. Anyone out there have experience raising the front of a CBR with 16" wheel? Thanks!

Aren't the tubes flush with the top clamp on the early Blades?
How far are you planning to raise it?

I just dropped the shocks off at the shop to replace the seals. The preload and damping adjusters extend well above the triple clamp and there's plenty of room to drop the shock tube.

Thought I'd raise it at least a half inch and maybe up to an inch if possible.

Half should be possible but I doubt there's room to go an inch.
When you mentioned bar risers I figured you were talking several inches :-)

Any motorcycle dealer can get risers for you. Gilles makes them.

Re: Raise the front of 94 CBR900RR; can't find bar risers

Thanks for the tip on Gilles but they don't have risers for my bike. You'd be surprised about the lack of bar risers for a '94 CBR900RR. Have done an exhaustive search for new and used stock.

I know I can raise the front - the question is has anyone done it and how did it effect handling?

I haven't tried it but I would expect the initial turn-in would be slower and then it would tend to fall into the turn once you had it laid over.
What you could try is dropping the tubes through the clamps half the depth of the upper clamp and then have 45mm tubes made to extend the tubes above the bars enough to put the clip-ons above the clamp. No idea if it'll even work but it would cost very little to try it. Cables and such may need to be extended or re-routed as well with raised bars.

Sure they do. The list 1995 but according to the part numbers, the 1994 and 1995 CBR900RR use the same triple clamp and bars.

Re: Raise the front of 94 CBR900RR; can't find bar risers

you could swap a 17" rim onto the front end to get that inch your looking for + the larger hoop has a much better selection of current rubber for the road and with the different tire profiles available you should be able to tweek these coefficients into your suitings... there's a lot of info on the web and especially this site to help you out with this, hope this helps you out a little bit

Swapping to a 17" wheel doesn't raise the bike much if anything at all - perhaps a quarter inch.

Re: Raise the front of 94 CBR900RR; can't find bar risers

Thanks everyone for the great tips. I've been able to use them to find some great options such as the F3 17" front, new triple clamp/streetfighter type bars or just knowing the Convertibars or Gilles for later years will fit. Now if I knew where it touches down in a slide I could figure out how to order sliders....

Re: Raise the front of 94 CBR900RR; can't find bar risers

The top of the fork tubes should be flush with the top of the triple clamp. It sounds like the previous owner raised the forks in the triple to try and speed up steering. Putting a 17" front will help a bit, depending on the tire you choose. I put a 17" on mine, and had no complaints with handling or comfort, so in order to keep the geometry the same as the stock 16"(with a 130/70), I went with a 120/65-17" tire ( a 120/70-17" will raise the front about 1/4 inch). I noticed almost no difference in handling. My bike still is very responsive, and maybe a little more stable at speed. But now I don't have to special order a 16" tire.
DO NOT drop the forks into the triple and then insert a bar to extend above the triple so that you could mount the clip ons above the triple clamp. You will not get enough surface area or clamping force on the bar by the triple, and it could twist out during some hard cornering/transitions when you really have to heave on the bars.

Re: Raise the front of 94 CBR900RR; can't find bar risers

Skater! - Thanks for the input on the 17" conversion. I'm seeing a decent selection of 16" tires out there. Mine is rock solid at speed and is too quick steering only in slow corners. Low speed steering is much quicker than my '87 CBR600. I'll probably get used to that. I'd only be interested in the 17" conversion if there was a dramatic change in the low speed handling. Without a back to back comparison it's probably hard to know what the difference would be. I had an '86 Yamaha FJ1200 with a 16" front that was very stable. The problem with that bike was it's weight. It just refused to change directions without a lot of pushing, pulling and moving around in the seat. Got so tired of that I swore off heavy bikes forever. Maybe one day I'll have something with no quirks. The '87 CBR 600 is good on most roads but in fast bumpy corners the old style forks start to complain.
