ogri Posted October 14, 2015 Author Share Posted October 14, 2015 The front wheel travels back as it goes up in the stroke of the fork, due to the angle of rake.Ok, so trail decreases as well as contact patch distance as the rake angle decreases upon front end compression. Right? STUFF EVERYTHING - I'VE ALWAYS GOT MY BIKE! Link to comment Share on other sites More sharing options...

Right? Well, I certainly wouldn't want anyone to confuse me with a chassis setup expert. I don't think the rake angle is ever decreased--as it is fixed by the steering head and triples--that angle is constant. But, since the forks are set at an angle (rake), then when the wheel travels up, it also travels rearward, hence shortening the wheelbase. Link to comment Share on other sites More sharing options...

Just trying to think through the dynamics. Since the bike is tilted forward under braking, the trail must decrease slightly, even though the steering head angle is fixed. With the build up of leaves and pine straw on the roads where i live, i will be cornering very carefully for the next few months. STUFF EVERYTHING - I'VE ALWAYS GOT MY BIKE!

Premium Member peporter Posted October 15, 2015 Premium Member Share Posted October 15, 2015 Yep, Ace Hardware 1/8" X 3/4" X 3' flat steel. A couple of cuts with the angle grinder and put the top of the passenger footrest on it to get the holes lined up, drill'em, bend the top down to make the angle, paint it and your'e in bidness.... Perfect, ill bust out the dremel tool and see what i can do. What length hose did you get the shock with, or was it just the statdard length?Standard length as far as I know. At the time I ordered, I didn't know there was a length option. Good luck, and be sure and post the results. Link to comment Share on other sites More sharing options...
com3 Posted October 15, 2015 Share Posted October 15, 2015 Yes. under (front) braking, the front end dives. Forks compress. Rake becomes steeper. Wheel base shortens. Under load, tire squishes, contact patch becomes bigger = winning. I work with top level US instructors and racers at the race track about 10+ days per month. You know, guys like Scott Russell, Ben Spies, Bradley Smith, blah blah blah. Link to comment Share on other sites More sharing options...

Bradley's voice might get a bit loud and squeaky if you call him American This signature is left blank as the poster writes enough pretentious bollocks as it is.

I worked with YCRS for 7 years shooting photos, videos, and getting to play motorcycles. He's been a guest instructor to the school. Link to comment Share on other sites More sharing options...
