Sachs shock spring

Does anyone know the spring rating for the Sachs shock on a '08 R312? It seems way oversprung for my weight (160lbs.)

Also, does anyone know who sells and/or rebuilds Sachs shocks?

Thanks.

Just a suggestion: Stick an aftermarket shock in there. Quite a few to choose from.
If I was to guess at the spring rate I'd say 1.05 newtons / mm. The Senna and Tamburini have a higher spec Sachs shock and that's what they have as standard.

Besides the Ohlins TTX, what do you all recommend as replacement for the Sachs shock?

Thanks,

Personally I'm on an Ohlins PBX 46 (Everyone knows that the TTX is only for bling merchants and girls) with a 9.5 spring, possibly you could get down to Mc Donald's for a few Mega MoFu Double cheeseburgers to soften the rear out a bit.

848SD;
the sachs shock uses a 160mm spring
the ohlins series 1091 springs are 160mm
their rates are from 54-110 N/mm, they are available from ohlins or PartsUnlimited dealers

Contact Lee at Traxxion. They sell Penske shocks which are some of the best. He can custom fit you for about $750. Just google Traxxion.

Thank you. I looked up springs in the part Unlimited catalog, but could not identify one that that fits purely based on what the catalog told me (i.e. fits this bike, this spring rate) as they list anything for MVs. What bike model would be comparable?

Thanks.

Thank you, I will check them out as well. My local racing hero/mechanic Jeremy Toye, recommended Penskes instead of Ohlins.

I wanted to re-spring the shock first as I really don't know how good that shock can be. Maybe it is a pretty decent shock for my riding once it is sprung properly.

Hey Ade,

I can't find the PBX 46 in their catalog, only the blingy MV788. Can you point me to it?
