Is this a significantly noticeable ‘benefit’, or a theoretical one?
When I went from my Rev 426swith the old motion control to the 2010 Teams with the upgraded dampers it was very obvious. (and both were in good nick, it wasn’t a servicing thing).
What was interesting (er, or maybe not, depends how nerdy you are) was that I ended up blowing up the compression damper in those Teams, and for a while had a standard issue motion control in them instead from an RL model, and tbh it made very little difference, I couldn’t say either was better or worse.
But the rebounderer, I think is very noticable- basically with the older fork, the bike handled the third decent sized hit in a row worse than the first, with the newer fork it works well throughout. Not that big a deal on, say, trailcentres or other relatively smooth surfaces where the fork gets recovery time, but when you’re chattering down a constantly rough track it adds up fast.
