Drafting

Could be KLR I suppose... What do you think?

I sat behind a truck at 65 mph for miles and about 1/4 throttle while riding my 1965 Suzuki 80. I finally backed down as was afraid that something might let go or that someone would move up behind and kill me if I lost draft.

Has anybody ridden close behind one of those semi trailers with the foldable triangular "truck tails" that are designed to reduce aerodynamic drag on the trailer? I haven't. Trying to figure out if they'd make turbulence behind the trailer better or worse for a following motorcycle. I've never noticed any difference in a car.

Guess I'll have to track one down on the KLR one of these days and get up behind it and find out for myself. I'm guessing since they're designed to reduce the "suction effect" behind the trailer, drafting wouldn't be as good behind one.

You could tape a short stick to your brake lever and ride even closer. That way when the truck hit his brakes and the bike closed the stick would hit the truck and apply the brake. It'd be like a crude ABS.
If anyone asks, you can say it's your draft board. ;-)

I've never tried it. I'm usually anxious to get out of the turbulent air, so I either pass or drop back

It's not the air which is the problem it's the err that will get you. ;-)

I've ridden behind a semi with the triangle jobby but not real close. It was a lot less turbulent but maybe I wasn't close enough to give you the answer you're looking for.

I find that the trucks with all the aero flaps don't blast you with wind like the ones without. I think they're great.
