I just bought a used Ohlins 46 PRC rear shock for my 2006 R1.

I have been reading for more than an hour now, and i can't figure out if this shock is sprung properly for me. The seller thought it was, but from what I have been reading, I think it might be too stiff.

Can you please point me to a spring chart for Ohlins' shocks, or otherwise help me figure out what the proper spring for my application is?

I couldn't find anything helpful on the Ohlins web site.
The Racetech web site says:
"Rider Weight: 170 lbs
Recommended Spring Rate for Street: 8.63 kg/mm (use closest available)
Stock Shock Spring Rate (measured): 8.6 kg/mm (stock)"

But I am too ignorant to know how to apply that...

I weigh 170 Lbs out of the shower, so probably 185 in full gear.

The text on the spring says 01093-36/105 L134


Thank you. I really appreciate your help!!!

1091-34/100 is an example of a code you will find on an Ohlins shock spring. Using the below charts you can ?decode? what you are looking at.
? The 1091 refers to the diameter and the length of the spring. Almost all Ohlins springs have a diameter of 57mm so that?s easy, the 1091 in this case means it has a 160mm length (when not on the shock)
? The -34 is the spring rate. For some unknown reason Ohlins uses it?s own numbers to label rate, but below on the rate conversion chart you can cross reference this number. In this case a -34 is a 100nm or 10.19kg or 571lb spring
? The /100 is the springs rate in Newton meters, but without the decimal. In this case the /100 means it?s a 100nm spring.

In this case the /100 means it?s a 100nm spring.

so this spring is too stiff for him?
how much is it to order just a spring?

1hander, Thank you VERY much. That is very helpful information.

So, in my case, it looks like I bought a 10.70 kg spring (600 Lb), and what I need is a 8.63 kg spring (485 Lb).

Does that sound right?

Don't forget to weigh yourself with all of your riding kit on,it makes a difference.

i reckon you need an 8.5 or maybe a 9.0 kg spring. the one you have is WAY too stiff for you.:fact

Thanks for the tip!


did you READ my first post? :2bitchsla

Hhhaaaahhhaaaaa


Here's a refresher:
"I weigh 170 Lbs out of the shower, so probably 185 in full gear."

Blur1 hit in on the nose. If that is a 10.7 kg sping, it's on the stiff side for you. Actually, very stiff, even for track use factoring in all your gear.

Should probably look into swapping the spring for something in the 8.5 to 9.5 range depending on intended use and rider sag. At 10.7 you are going to have a time trying to keep your geometry consistent being unable to keep the front and rear prett close in travel.

Whatever you do, don't lower the front end (pull the forks through the tripples).

Should be an easy swap.

Hey if your happy with Probably.
Personally if I'm taking the time to set my bike up I'd like to know for sure.
Good luck.

usually if you buy it new, they'll swap it for free. It looks like the 04 and up uses spring rates that are softer by .5 than the 98-03 per given rider weight.

Is that because the bikes are lighter?

I don't think so, maybe graves found something better with a softer spring. But I've seen many threads where the given weight and the spring they got with their graves modified shock which was for "their weight" to be .5 lower.

At canyon blasting speeds I ran a 9.0 spring on my 99 and now a 10.1 on my 04 and both feel fine/great to me. So again I dunno :dundun:

 

[299]

does the weight comprise of the machine laden plus the rider and pillion weight and other accessories tat the bike might hv on it?

 

[1hander]

yes
