BUMP!

I'd like to know the same thing.. Will heavier riders still need to spend a mint on new suspension since at 250lbs you're beyond the range for what comes from the factory...

Inquiring minds.. and all..

OK - I am NO AUTHORITY... but I'm betting that the larger diameter forks will need the same range of springs as those needed on the 41mm or 43mm forks.

From an engineering perspective, the diameter of the fork tube would have nothing to do with the ability to have more adjustment for setting static sag.

I have a friend who races with us and he's um... er... well... he's more than 10 pounds bigger than I am. He definitely needs more appropriately sized springs on both ends of EVERY bike he rides on the track (S1, XB12 and the poor little Blast). We put him on the saddle with all his gear and try setting sag on front end at 35mm, 25mm rear and just cannot do it because he squashes the springs too far - meaning he needed stiffer springs. (OK, he's on a diet but he is a very real 230 pounds, down from 260 last year)

For "non aggressive" riding, I'm betting you're going to be fine but if you are wanting to dial in the suspension and ride hard in the turns, braking and throttle-in-turns, you might need to consider re-springing both ends. That's just true in any suspension on any bike (unless you get a set of some yet-to-be fielded on motorcycles, miracle, computer-controlled, gas-springs... but that's kinda "out there")
