    I am slightly more than that, and I have a '04 s model (probably springs are different)

    Long travel bikes have softer rear spring

    Since i've posted up a few questions in this thread myself a few pages back, i'll give you all a short results update on what i did. I just got my suspension from George at Suspension 101, and it's crazy awesome now. Yes it was expensive, but so well worth it. So whatever advice that @Torque is giving out here, from my experience with his work, it's probably spot on. The only, and absolutely only thing that i think he needs to change, is to have his fork stickers made in an orange color.

    Mid-summer, I replaced the OEM shock with a 990ADV unit on my 950SE, after having Rob at Lang's Off-Road install the taller spring, redo the guts, etc.

    Took it out on the Oak Ridges-Ganaraska Trails and in two minutes was laughing out loud at the bonkers difference. I could sit down! In the rough! And without rendering my spinal cord into splinters. I could roar up and down nasty boulder strewn hills at full speed like those boulders were party balloons. I also stopped airing down, running street pressures in my Tractionators. And that was pure Grrrrrr.

    Chappies, I could go faster over and through everything wet, dry, hard, soft, sandy, muddy, twisty, turny. My confidence levels smashed through the glass ceiling, or whatever that thing up there is. There wasn't one hooligan move that wasn't made 40-50% easier on the filthy beast. Even street hazards got tamed, seeing how many of Toronto's roads are more busted up than Ontario's trails.

    Except... now it's so effin tall -- guessing two inches more now -- that I tipped over a few times in trails at low speeds because there was no there there when I put a foot down. I dialed the screw down as low as I could and backed off a turn or two, but that made no meaningful diff. I've got a 32" inseam, which doesn't help. I've ordered a new one, but they're backlogged. I also just switched to new Sidi boots which are substantially lower than my old cheap but bomb- (but not water-) proof Alpinestar Tech 3s, with their amazing short man remediation treads.

    Anyone who's done this mod encountered / solved this extra question thing to their satisfaction?

    Can't really tell by looking, but here's a gratuitous porno pic with aphrodisiac to set the mood...

    On my 950A I removed my seat cover, dished out some of the foam, then stapled the cover back on. It definitely changes the seat to footpeg distance, but at least i can get the tip toes of both my feet down now.

    Did you match the additional travel in the rear by extending the travel in the forks?

    Either shorten the shock or lengthen the forks. Surprised your not getting head shake. Can shorten the shock some but have secondary bottoming system that you have to be aware of. Do not want to go into that system too early.

    Lengthening the forks? To make the bike even higher?

    I stand 95% of the time. I very rarely sit. It's definitely a trade off, but i'm in good enough shape that it hasn't been an issue for me (yet).

    Youre steering angle will be much sharper with the ass so high and unmatched on the front.
    Take care you dont end up in a tank slapper.
    You really need to shorten the shock or lengthen the forks to match.

    OEM Height for now, we will adjust it to his weight at some point.
