tyresup Posted May 2, 2014 Report Share Posted May 2, 2014 Hello guys. I picked up a 2013 Evo 300 and am wondering rider sag numbers on the rear shock. I know it's 1/3 of shock length but have no idea what this is in mm or inches. Anyone here know? Thanks Quote Link to comment Share on other sites More sharing options...
thesolidman1 Posted May 3, 2014 Report Share Posted May 3, 2014 Rear wheel travel is 7.1" or 180 mm. I would not set it at 1/3 of travel <not shock length> unless you are extremely light, that is a dirt bike setting, not a trials bike setting.

tyresup Posted May 3, 2014 Author Report Share Posted May 3, 2014 So about 60mm? Thanks Quote Link to comment Share on other sites More sharing options...
thesolidman1 Posted May 4, 2014 Report Share Posted May 4, 2014 No, I would go 85-90mm Quote Link to comment Share on other sites More sharing options...
0007 Posted May 4, 2014 Report Share Posted May 4, 2014 I dunno man Here's my thoughts on the purpose of sag I'm traveling at high speed and I hit a hole, sag allows my wheel to drop into the hole so the entire bike does not, to maintain traction And at high speed it allows my wheel to drop into the hole so I don't feel the bump Due to the low speed nature of a trials bike, the purpose of sag is not the same as a MX bike So why use the same theory?

I like that theory(in reverse). I trials you need more sag because the average bump is bigger! Quote Link to comment Share on other sites More sharing options...
thesolidman1 Posted May 4, 2014 Report Share Posted May 4, 2014 What makes you say the same theory is suggested? I'm suggesting NOT using the dirt bike theory of 1/3 of the wheel travel. Quote Link to comment Share on other sites More sharing options...
billyt Posted May 4, 2014 Report Share Posted May 4, 2014 (edited) Sag is just as vital to a trials bike as it is too any type of bike be it motorized or not. If it has suspension it needs sag. Why, any bike traveling along does not start necessarily moving the swing arm in the compression direction. if there is a hole in the ground the wheel drops into and the swing arm is opening up causing the shock to extend and there fore it needs be controlled in extension. The sag also helps take into consideration the riders weight thus where the shock start working from. Edited May 4, 2014 by billyt Quote Link to comment Share on other sites More sharing options...
