What are the effects of rake and trail on handling?

Since a motorcycles handling is affected by this geometry which way would you move things to have a specific effect?

If you have a greater offset between the steering stem to the fork tube centerline does it make the bike handle better at lower speeds?, higher speeds?

I would guess that a trials bike geometry would be best at low speed control and a road race bike best at higher speeds. Anybody with some knowlege in this area please put in your 2 cents worth especially concerning different fork setups on the SV.

Thanks,
Zak

1)Has anyone have or know of a spreadsheet or a calculator for rake and trail changes for gen II SV650?

2) I've read that many riders on this board adjust the triple clamp settings to 5 to 15 mm fork exposure from stock (flush with clamps). How do you like the settings and what if any stability issues have you encountered at different settings?

They state "If you use a very fat rear tire, you should keep the trail as close to 4 inches as possible." What exactly is meant by a fat rear tire? 180? 210? Just wanted to know incase i decided to go with a 180 rear.

Now I now to start measuring when I decide on doing that swap.
imho, on a 17" rim the division between fat & skinny is 160/60=fat 150/70=skinny

Okay, got tired of waiting :BangHead:- went looking on my own... :confused2:

Excellent explanation of rake and trail:
http://en.wikipedia.org/wiki/Bicycle_and_motorcycle_geometry

Rake and Trail Calculators:

http://www.rbracing-rsr.com/rakeandtrail.html

Another rake and trail calculator:

And another calculator:
http://kogswell.com/geo.php?e1.x=19&e1.y=20&h1=690&i1=73&j1=45

Still, this info doesn't solve the human factor in the equation: How do ya'll like the effect of fork offset in the triple clamps - forks at 5mm, 10mm, 15 mm above the triple clamps, etc.?
