BLOODY 22 STONE ffs you need proper suspension.

Ohlins don't cater for anyone over 17 stone.

TBO when I had it I was thinking of binning the Ohlins and getting Hyperpro units, which is what I had fitted on my BB.

Oh and yes I know, lots of suspension tuners rubbish others choice, after all they only all want to rip us off.

The main thing that needs changing for (ahem) heavily built chaps is the spring rate, and you can get standard 2.25"/58mm i.d. shock springs in rates from anything from 100lbs/in (1.8 kg/mm) right up to 3000lbs/in (53.5 kg/mm). At least you can at the place I use. This range would cater for a mosquito right up to an elephant (or a Willopotomas). Standard rate on an Ohlins RSV shock is 542 lbs/in (9.7 kg/mm), by the way. The valving would also need changing, but it's all well within the capabilities of a shim stack.

So to say "Ohlins don't cater for anyone over 17 stone" is inaccurate, to say the least.

And while I too have a high opinion of Hyperpro gear (I use their progressive springs in my Falco forks), Ohlins kit is also top notch. Get it set up (and probably re-sprung and re-valved) by someone who knows what they're doing and all will be well.

To be honest, I'd be very tempted to stick the spring off a standard blue spring Sachs shock (800lbs/in or 14.3 kg/mm) on the Ohlins and see how Will gets on with that; at least it would provide an indicator of what spring rate might be needed. If it's too harsh, something in between the Ohlins and the Sachs rate would be needed. If (heaven forbid) it's too soft, go up further on the spring rate.

Once you've got the shock off, changing springs over is a piece of piss (unless you have a hydraulic ride height adjuster, of course) and only takes 10 minutes at most.

Bugger.. That's fucked that one then..

Will wait and see what Griff has to say. Unfortunately he's not working weekends in the foreseeable future, so will have to try and blag a day off work at some point.. Hopefully when the weathers alright..lol..

Bugger. As you so correctly say...

My Ohlins has a HRHA and the only way to change springs is to use a man with a fairly specialised piece of kit (hydraulic press with specific fitments). If you have one of those (or access to one) it should be possible, but bear in mind that you are dealing with large amounts of kinetic energy in a compressed shock spring.

Rob Mawbey of Racing Lines in Derby ( http://www.racinglines.co.uk/index.html ) can do it for you, as could John at Revs Racing in Halesowen ( http://www.revsracing.co.uk/ ). Rob is open on Saturday mornings, and I think John is as well, although it's best to check first.
