Member Contributer YoshiHNS Posted October 18, 2013 Member Contributer Share Posted October 18, 2013 I have a WP suspension spring and am looking at other OEM springs of theirs. I am not entirely sure how to read their numbers. For example, the one shock is marked 85-160. I've read that the first number is N/mm, and the second is the spring free length in mm. 85N/mm = 8.66kg/mm? That seems really really light. The stock VFR is 15.3kg/mm or thereabouts.

V4 Rosso Posted October 18, 2013 Share Posted October 18, 2013 I've read that the first number is N/mm, and the second is the spring free length in mm.That is correct. That spring did not come off a VFR shock did it? Link to comment Share on other sites More sharing options...
Member Contributer YoshiHNS Posted October 18, 2013 Author Member Contributer Share Posted October 18, 2013 No, the 85-160 isn't off of the VFR shock. The one on the VFR shock is 165-150. The 85-160 is off of a sportbike and I thought it would be heavier. Link to comment Share on other sites More sharing options...
Baileyrock Posted October 18, 2013 Share Posted October 18, 2013 Basically No sport bike spring will be as heavy as even a stock VFR spring. It's a combination of both bike weight and rocker ratio that make the VFR spring stiffer than most other bikes. Link to comment Share on other sites More sharing options...
