Rob, do the maths with him, Ha Ha! and now listen to the sag he suggests is good for this bike with standard suspension in it, O I love the USA way of doing things

The front looked like it was (excuse terminology) under damped (ie. overshot then had to come back down).

Is there a correct way to statically test compresison and rebound damping?

well spotted, also his arithmatic does not add up, and std is that soft any way, that to set the front ( Especially) to the numbers he suggests, would have the thing turning in that quick, with No travel left, or not a lot any way.

Messuring a tech messurement from the centre of the axle, ( with out a centre tool/point) that is also very hit and miss, could be as much as 2-4 mm wrong!

Tech NO, but people with TRUE experience, can have a feel, and have a very very good opinion of what it is like, The best way to do what you have asked, is have your shock put on a shock Dyno to map what the comp and reb does Via the graph that gets printed out

OR hire me to test ride it for you!

That bike is going to stand up mid corner in transition. And using the top of the rear axle as a reference point?!!!!! Every time you adjust the axle its a new set of numbers. No allowance for rear subframe and tail section flex....
And this is the same guy that is a doubter of top out springs, probably because its too much work to change them....

Na, its a piece of piss. Jay Lawrence showed me the awesome cable tie & dog leash arrangement he has on the old BMW & how simple it was just to yank the cable ties a bit more, he even offered to build me one, but i didnt want the dog running away.
Hard to argue with a guy that was getting an aincent BMW around Manfield as fast as Stroudy was on a brand new FZR1000 back in the day.

Ha ha indeed, but the odd crash does help you go faster if you really want too

I know bugger all about suspension, i know what feels safe & good to me & know how to make my bikes feel that way.

Ive been pondering this for a couple of days & i really need to ask these questions.
Is Ohlins suspension, or any brand for that matter, so finicky that 2mm (thats less than half the height of the words you are reading) makes all the difference between awesome & shyte? can the average, or above average rider tell the difference? & if so, must the suspension be ajusted before & after the rider takes a shit? (it would need to be if 2mm is relevant) Does the "perfect measurement" work for all bikes & all riders for all surfaces & tyre combos? and if these magic measurements are gospel, who decided they work best & why?
Does this mean that all bikes must be set up the same to a tolerence of far less than 4mm or otherwise the racer will be compromised?
All serious questions i would appreciate answers to.

**Ragingrob** · 22nd November 2009, 14:04

Hey Shaun/Robert do you have any idea when you're next appearance up Auckland way for a suspension set-up day would be? I'm so keen to get mine checked... Don't really wanna trust anything online and try it myself eh...

**Nonbeliever** · 22nd November 2009, 15:39

His first mistake is having the bike sitting in that wheel chock.(which is elevating the front end over the rear therefore affecting weight distribution).

1) NO mate, but detail is important to the mind set of a rider to go very fast

can the average, or above average rider tell the difference? & if so, must the suspension be ajusted before & after the rider takes a shit? (it would need to be if 2mm is relevant)

2) Depends if it was a solid or a Beer squirt (NO MATE)

Does the "perfect measurement" work for all bikes & all riders for all surfaces & tyre combos? and if these magic measurements are gospel, who decided they work best & why?

3) Again ( NO MATE) They are used as a tool for a starting point, then adjusted to suit the machine, tyres, rider, etc, having said that, manufactures of any thing, always believe they know best!

Does this mean that all bikes must be set up the same to a tolerence of far less than 4mm or otherwise the racer will be compromised?

4) You know the awnser AGAIN

All serious questions i would appreciate answers to.

What are doing pretending to read and think again

He's not as stupid as he looks. By facing the bike to the right the gravitional offset between the front and rear wheel is negated by the earths rotation
