Tpo speed: 118.7

1/4 mile: 13.11 @ 96.2

Still haven't found 0-60, except anecdotal, 3-4 seconds.

No HP or torque curve either.

Found this at '84 was the last year for the Standard version of the GL, and I'm thinking these numbers aren't for the dressed version.

There's immense drag, ive ridden without it. Mainly the windshield and Id hate to be without that - i got spoiled when switching to fairing bikes early on. I suppose a "buddy shield" would do the trick if one didnt mind the shorter windshield. Passenger would get drowned in the rain.
