MC21 steering damper

Thu Jul 03, 2008 9:15 pm » Post: #1 » Download Post

Hi, Always liked the idea of a steering damper but never got round to having one.
I do like the the bike shaking its head when stuck on. (makes me laugh).
Think they look nice?
Are they worth having?
What makes are good other than the obvious (ohlins)?
What stroke would be ideal?
What about mounting brackets who makes them?
Thanks, Grant.

I've got a Sprint damper that I'm going to fitting to my NSR shortly, and I've used them before. Decent cheap alternative to the usual Ohlins, WP etc. I bought it for a different bike but theres enough stroke on it to run it on the NSR, as long as I set it up in the middle of the stroke. As long as its got enough stroke to go lock to lock it'll work fine.

Demon tweeks do fork clamps for about £20 I think.

Just ordered a 120mm Ohlins the other day. Very Happy I measured from the mount on frame to the fork leg with bars turned all the way to the right. Then I measured the same points with it to the left. I took the difference to get the stroke.

Harris peformance makes the bracket for the fork. https://www.harris-performance.com/website/frameset2.htm
Search for fork leg clamp. The bracket that holds the damper should be included.

I noticed that people mount them different. Some people mount the eye on the damper to the frame and others mount the eye on the fork bracket.

I should have mine on Monday, will let you know if the 120mm is a good size & how I mounted it.

I've found it depends on how it fits in reference to your fairing and leg. If you fit the body to the frame it means the shaft moves backwards/forwards and left right in relation to the frame when you turn the steering. This can fowl the fairing or come too far backwards and catch on your knee. Whereas if you mount the shaft to the frame the body moves backwards and forwards, and the shaft end (fairing end) left and right in relation to the frame.

Most of the steering dampeners have the adjustment either by turning the shaft at the opposite end to the eyelet, or at the back of the body, meaning it's not easy to adjust once seated on the bike if you mount the shaft eyelet to the frame. If you mount the body to the frame you can generally adjust whilst on the bike.

I've mounted my Ohlins body to frame, as it doesn't fowl the fairing or my knee, and allows for easier adjustment. All of that said, I am not sure the NSR really has a problem in regards to headshakes? But having nearly had an off with a violent headshake on an Aprilia RS250, I think it's cheap insurance, and they look the business.... Smile

Did you find out if 120mm stroke was a good size to go for?
Also how did you end up mounting it in the end?

Also what overall length would that be? (Lots of them listed on a certain auction site dont list the stroke).
