Transitioning to the Dark Side - a Detailed Log
Written by jprelock on 4/1/2011 at 05:30 am

It's kind of interesting actually. Pressing down hard on the inside peg
allows the bike to turn in very quickly, almost wobbly, because all your
inputs are going in the same direction. Pressing down on the outside peg
creates an isometric movement where you're stabilizing the turning in motion
with opposing forces, which does make turn-in a little slower, but you can
bring back the speed with more force at the bars. One might ask why would
one want to do that. In addition to potential more control over turn-in,
one theory said weight on the outside peg allowed better feel and control
over a sliding rear tire.

Purpose: I put a car tire on my back wheel 2 days ago. I hope to provide a detailed post of the experience, good and bad, in order to provide as much information as possible for those considering a similar move. Disclaimer: Riding a motor

    I plan on changing tires this weekend on Obsession, although sticking with Dunlops. As part of my science experiment I will be trying to mount my tires myself using only my Cycle Pump from BestRest and their Bead Setter gizmo:

    I was the one who made the "knife edge" analogy soon after putting on the same tire you did. Maybe I've just gotten used to it but I don't have that sensation any more. I have had a few instances of the bike slipping a skooch on rainy

      Bart, Thanks for the report on the Battleax. I will be looking to replace my front tire toward the end of the season and was thinking about trying one. Also appreciate the notes on your experience on cornering. The biggest concern about da

    I had the BF Goodrich mounted last week, but I have not had a chance to try it out yet since my bike is still apart while doing other maintenance/modifications. I ordered the tire from Walmart using the free ship-to-store option. Total was $9

      My first impression of mounting a car tire was "why", are they crazy? But it sounds like your reason is that it offers much higher mileage than motorcycle tire do. I have always felt that motorcycle tires wear out much too soon also,

            That photo in the Dragon is scariest of all. When you see how far over that bike had to lean to make that curve compared to all the other bikes, you'll realize that curves are not what those darkside tires are good at. John Handford,

              I have to disagree. The lean angle for a give bike and rider position is just a function of speed and radius of the turn. He was going fast! Anybody else going that fast would also lean that far. --- In

                Ah contrare! I am a former (very old) road racer. To lean the bike over less, all you have to do is get your butt off the seat and slide it to the inside and put all your weight on the inside foot peg. Once you do that the bike will lift up a

                  Well, David did say for a given rider position, but I was sort of thinking the same thing, how do you know exactly who is hanging off how far if it's only subtle? And the technique you describe works as well if you put weight on the outside p

                Sorry, The shape of the tire is a major factor in the ability of the tire to negotiate a turn. When you are turning, the inside radius of the tire in contact with the road is shorter than the outside radius of the tire, allowing your tire

                  We are not talking about the same thing. My statement was only about lean, nothing else. I carefully specified that my statement applied to a given rider position. Once the rider position is determined the motorcycle and rider can be treated
