when we pack our bikes how many of ours test the breaking to see which way it will shift or will it come out from under us?
testing is one of the best things we can do every trip I now have to add everyday expect the bike to become a squeal and are you ready for that bike to jump or almost go down on us?
I was lucky twice in one week I have had my skills tested by the road and bike I had to go around to see what it was wrong to only see the road had cracked wide enough to get me my front tire just followed that F---- crack but I was a lucky one I managed to ride it out.
I guess the real qa is are you that quick to be able to save yourself and the bike? I thought I was on a horse again what a ride.

John-
You left out a VERY important
fact here.
Semi trucks are designed to
stop 80,000 loads and the brake systems are set up for that weight. When the
truck is empty, it is vastly overpowered concerning the braking system. You pull
out in front of the truck, the driver hits the brakes to avoid you, and the
brakes lock up resulting in an uncontrolled skid. Not a good thing. Those double
aluminum bulk trailers you all see only weigh 22,000 punds on a brake system
designed to stop 80,000 pounds. Think about it!!

GENERALLY CONSIDERED TO BE 3/4 OF A SECOND FROM THE TIME THE
HAZARD IS SPOTTED, UNTIL THE TIME THE DRIVERS FOOT TOUCHES
THE BRAKE PEDAL.
BRAKING
DISTANCE
TOTAL FEET TRAVELED FROM THE TIME THE
DRIVERS FOOT TOUCHES THE BRAKE PEDAL UNTIL THE VEHICLE IS AT A
COMPLETE STOP.
TOTAL STOPPING
DISTANCE IS A COMBINATION OF REACTION TIME
DISTANCE AND BRAKING DISTANCE.
MILES PER HOUR
TIMES 1 ½ EQUALS THE FEET PER SECOND THAT THE
VEHICLE IS TRAVELING.
(MPH X 1.56 = FPS.

TIMES BELOW SHOWS BRAKING

INFORMATION FROM Lawyers and
Judges publishing. com “vehicle speed and stopping distance
computer. “
Large SUVs’ & light
trucks (weighing 8,000 – 10,000lbs) must
be able to stop within 280 feet of braking
distance.
Large SUVs’ and light trucks
weighing at least 7700 lbs must be able to stop within 204 – 218
feet.
ALL NEW vehicles weighing
less than 7700 lbs, (cold brakes, dry
road, new blacktop) requires a minimum braking distance of
230 feet.

INFO FROM MOTORCYCLE CONSUMER
NEWS WINTER 04/05 PERFORMANCE INDEX
`MOTORCYCLE-TYPE
TRIKES RAY,WHO
OWNS A TRIKE DEALERSHIP IN WASHINGSTON STATE, AND WHO WORKED
WITH THE EVERGREEN SAFETY COUNCIL PREPARING THEIR TRIKE &
SIDECAR COURSE, SAID THAT A MOTORCYCLE-TYPE TRIKE( NOT A
CAR-ENGINE MADE INTO A TRIKE) SHOULD STOP IN A SLIGHTLY SHORTER
DISTANCE THAN A 2-WHEELED MOTORCYCLE OF THE SAME BRAND AND
MODEL. THIS IS PROBABLY BECAUSE WHEN A MOTORCYCLE IS
BRAKED HARD, IT NOSES TOWARD THE FRONT, AND THE FRONT
WHEEL HAS TO DO MOST OF THE BRAKING, AND THEY FOUND DURING
THEIR TESTING THAT WHEN A MOTORCYCLE-TRIKE WAS BRAKED HARD THE
BACK-END SEEMED TO SETTLE IN SO THAT ALL THREE TIRES WERE
BRAKING, WITH THE BACK WHEELS DOING MORE OF THE WORK.
