Can't believe Erionblade didn't respond to this post. Being you were riding a “couch†and all.
Dude, glad you and the bike made it through without a scratch.
Hard to say, everything everyone is saying is true.
Have seen many guys that say they were leaning and do the exact same thing. I believe it was initially all about the body position. The speed you carrier into the turn seemed reasonable, but the turn snuck-up on you and you were not prepared. I mean you were on top of the bike. That is where you panic dude, instead of leaning with the bike you made every effort to lean the bike but you failed to fall with the bike. This would have given you the feeling of max lean and the bike not turning. Letting off the gas and even braking with the front compounds the matter by loading the front end.
My advice, for what its worth:
Proper body position prior to the turn will help you gain the confidence to fall with the bike when it is time. Lift the ass, get it off the seat, that will weight the inside peg. I believe you that the bike was leaning, but you were still on top of the bike countering the bikes lean angle. If you don’t believe me, find yourself a passenger and tell them to lean against the turn while you try to lean and steer the bike around a curve. You'll will experience the same feeling you did that day.
Second, I suspect that your front forks may need to be adjusted stiffer. I weight 210 and could not get the stock forks even close to proper sag adjustment for my weight. Dude, if you’re going to play aggressively in the twisties proper adjustment of the bike suspension is a must.
Oh BTW, standing the bike up prior to existing the rode. Good Idea!
Last note: I prefer to adjust my rear brake so that it will not lock up EVER. I tend to drag the rear brake at times to scrub of a little speed entering a turn. I never depend on the rear brake for stopping power, so why have it adjusted so tight??? Having it adjusted this way allows me to reduce speed by a few mph without the fear of the brake locking.
May not be in any book but it seems to work for me. If I need to slow even more I resort to trail braking.
Again Train, glad to see you are doing well.
