i have 2 questions about ohlins road and track


-whats the "max ride height" vs oem shocks ?

-whats the weight vs oem shocks ?

SakeBomb Garage

Weight is about 15 lbs lighter that stock, ~50 to ~35 lbs. Ride height can get to at least stock height. PM for best pricing if you haven't ordered your kit yet, we will price match anyone and offer exclusive upgrades like rear remote adjusters and low profile mounting forks.

JRC

But, there is a recomended height by ohlins and it is lower than stock, correct? Is there any issue running the stock height with the ohlins. or at least, is it better to run the recomended instead of the oem height?

I´m also interented on pricing by I´m in Spain, I don´t think You can ship them here.

Thanks

Right, according to ohlins manual - in it's standard positioning it is 25mm lower than stock with an adjustment range of +/-15mm of the perch from the standard position of the assembled damper. Since the shocks are not positioned perpendicular to the ground, the ride height range effect is really the (15 sin θ)

Definitely you do not want to run the damper out of it's performance envelope unless you want to be left high and dry on warranty or bust seals.

Changing ride height via the lower perches will not in any way harm the shocks, or even change the resulting shock movement over any given bump.

so what your saying is at "max height" the ohlins will be 1cm shorter than stock , correct ?

Thomas has a point that ohlins has ride height adjustment in the lower cups

Not being familiar with the dfv I don't know how much space there is to adjust.

But you obviously don't want to short stroke the suspension and you don't want the damper to be riding on only 2 turns of thread just to get to stock ride height.

But according to the manual, their suggestion is no more than 1cm less than stock so your interpretation is correct.

The front shock:wheel motion ratio is ~ 0.59:1

The rear is ~ 0.58:1


With all of Ohlins' recommendations, you will be 1" (25mm) lower than stock at the wheels.

So set the front lower bracket height 0.59" (15mm) longer than they show.

The rear. Either:
- set the bottom bracket length 0.58 (14.5mm) longer than they show.

- or better yet, preload 0.58" (14.5mm) more than they recommend. You'll end up with 16.5mm of preload. They recommend 2mm. You're adding 14.5.

Voila. Right around stock height.

Simple.

Car Analogy

Curious, always trying to learn, why preload rear to get stock ride height, but not the front? More bump stop clearance?

B serious

The front shocks have so much travel before they touch the bumpstop that its crazy. More than stock, in fact. So preloading the front isn't necessary or recommended. If the shock has too much travel, it won't control excess roll...and the tyre will strike the inside of the fender before the shock will complete its motion.

The rears, however, have very limited compression travel. So using some preload helps.
