NEW PRODUCT: Race Tech Bottoming Separators

Recommended Posts

Some PR from a long-time ThumperTalk sponsor that I want to share...

 

 

Add increased bottoming resistance and damping control on the second half of the stroke.  Now available from Race Tech are Bottoming Separators for Showa TAC forks (KX450F, RMZ450), Showa SFF Spring Forks (KX250F, RMZ250), and Showa Triple-Air Forks (CRF250R).  Race Tech has two variations, one for Motocross and one for Supercross to control damping and prevent from blowing through the stroke. These bottoming separators are reversable to provide two positions of engagement with 20mm of difference.

Anybody got any more info on these, are these like huck valves? Or just funny shaped hydraulic cups or something different again?

no, it has nothing to do with huck valves.

 

@Cardinale199 testet and used stuff like this in the first year when the SFF fork appeared... He may has more to say about them.

 

Generally they dip into the oil in the outa chamber and displace oil by volume, which results in damping.

Usually bottoming rings work through a clearance which acts similar to a fixed orifice (eg the ring at the end of a CC forks cartridge).

These rings may also use that principle to a certain extend but the main part would be volume deplacement imo.

Thanks for posting Bryan.

These are completely different than huck valves.

 

Forks come with bottoming separators stock, but their OD is smaller allowing fluid to flow much more freely between the separator and the fork tube.

 

These are similar to what is used in A Kit suspension and used to control damping approximately 50% of the way through the stroke.  The OD of the Race Tech Bottoming Separators is larger to force fluid through the fins.

 

We have versions for Supercross and Motocross that are different, the number of grooves determines the amount of damping provided.  Also, they are reversible to engage at different times based on your setup needs.

 

Hopefully that helps!

Thanks for the explanation, makes perfect sense now. I'm running ohlins cartridges in my showas though, so this setup wouldn't work for me.

its not only the od... if it would be only the OD, the longer version of the  separator would make no sense. OD = anulus restriction; therefore you dont need a long distance, the restricting area would be ID fork leg - OD plastic piece aka restrictor.

However, showa uses the longer one in stock too. It displaces more VOLUME, which also creates damping.
