Fork springs for heavier riders - 9/13/2006 3:36:55 PM    kevinedgington Posts: 35 Joined: 9/12/2006 Status: offline I've been reading posts that say the fork springs in the CBR1000RR are for riders around 150 pounds. OK so I admit, I'm almost 100 pounds heavier than that. So I throw this question to the experts: What would be the best fork spring setup for me to switch to? (Sufficient details/leads/links would be appreciated.) Thanks in advance! _____________________________ Live to ride.

I notice a lot of dive in the front end under even mild braking, and with my girl on the back it is even worse...really hard on the arms and wrists. Once again guys, THANKS!!! _____________________________ Live to ride.

RE: Fork springs for heavier riders - 9/15/2006 9:17:25 AM    kevinedgington Posts: 35 Joined: 9/12/2006 Status: offline I set my preload higher at one point, not knowing that the darn bike was made for a 150 lb rider, but I didn't go all the way. I'll crank the preload all the way up for now, until my shop is built, then I'll do the fork spring replacement. BTW, visited all the links offered up by you guys and learned a lot. The tutorial on how to change the springs was downright awesome. _____________________________ Live to ride.

I put in beefier springs along with the valves. That made a huge difference. (in reply to kevinedgington) Post #: 9
