Hi John, happy new year! I noticed you have one of these on your bike when I was looking at your steering bracket pics. Obviously your happy with it, what stroke did you go with? 120mm?

Thank you sir.
Shawn

Hi Shawn

HNY!

Mine is an LSL damper. 130 mm piston length and a 90 mm stroke. A 90 mm stroke is perfect. I think a 130 mm piston is the minimum you can get away with. At full right lock I have about 20 mm of piston left at the end of the damper.

A 150 mm piston with 90 mm stroke seems to be the damper used most often. 150 would let you postion the fork clamp end a little more ideally than mine is located.

This is full right lock on a steel frame bike. Alloy frame bikes will have the bracket farther aft on the frame and will require a longer damper piston to accomodate that distance.

O.K. Sounds like I would be better off with the 90mm stroke as I'm using the aluminum frame. Do you think the inverted R6 front I'm using would also factor in on this? Maybe I should order the tube clamp first and then try to mock it up for a measurement before ordering the a cylinder?

All good Jon I have an RZV (JDM aluminium frame) so you think 150mm/90mm stroke would be best for that frame? Also, where did you get your damper from and is possible to run something modern like an Ohlins on your brackets? Lastly do you need to purchase bespoke fork clamps along with your brackets and damper of choice or are their universal standards

EDIT: I just checked to make sure I was giving the right info,I wasn't :mrgreen: I'm using a 130mm stroke damper, You need this length if you side mount the forkclamp like in the pics, I hit lockstop to lockstop and have roughy 2mm left on the stroke each way. I find the side mount makes more use of the damper, My forks wont budge a mm if I set it all the way to the hardest position..
You can use a 90mm is you have the clamp pointing straight back at the damper as the pivot point will take up a lot of the stroke.

This is the damper I use: http://www.fastfromthepast.com/odm3090e


I use a 130mm for my R6 front end,, Works great..

It doesnt specify piston length but is this the ideal one?

Paul

When you put the bracket on your RZV frame were you able to calculate the length of piston needed to maintain the 90 mm stroke? The photos you sent me of your RZV frame look to have the bracket about 50 mm farther aft on the frame rail compared to the RZ500 steel frame. Do we have a solution yet for a damper length and stroke for the RZV frame?

John

I did John. The 130mm works perfect. I popped the damper of the RZ and rough fitted it and it works great.

I suppose that if the frame bracket is farther aft on the RZV frame you just have to move the damper bracket farther back on the damper body using its attachment clamp, as shown in Tacky1's photo above. It could be right at the end of the damper and still work perfectly, like this (that image also shows correct fork clamp positioning...more on that below) http://www.fastfromthepast.com/steering-dampers

The damper itself stays in the same position as it would on the steel RZ frame, but the clamp attaching the damper to the frame bracket is father aft. You still have the full 90 mm stroke.

Using a fork clamp with a good sized boss should provide a little extra length to help positioning.

As far as positioning goes and to ensure proper damper function, LSL says that with the front end pointed straight ahead the fork clamp attachment point should be 25 degrees to the aft outboard side for proper damper function. The concern being that as you increase the distance between the damper mount and the steering pivot (fork attachment) the damping force rises disproportionately. By having the steering pivot attachment point just slightly offset (outboard) of dead centre aft on the fork you avoid that possibility. That is how mine is mounted in the photo above.
