aerodynamics

Post by lucky77 »

Anyone got any good tips for better aerodynamics work on the zxr? also anyone know where to get a tail with undertray rather than having a gaping hole causing huge drag! :)

Thanks in advance

put a double bubble screen on it, and also check your clothing as thats what the air hits is it not?

I second the clothes thing: in tight jeans and the jacket from my trackday 2 piece mine has touched 141mph, with a tail pack no less. In my winter textile suit i struggle to reach 125mph, you can really feel the pull on your shoulders. If you've got about 80 squid spare try getting a rear view camera instead of mirrors. The camera, with infrared leds for night time, can be an 18mm bullet shape that sits in a hole in your tail, with a wide angle lens, and you run one cable to a sat nav size screen you mount above instruments, with one cable plugged into a 12v line. Short of moving the exhaust to be under the belly (ktm rc8r style) this will probably make the biggest improvement. Oh, and there's a guy who makes carbon fibre fairings without the fake ram air intakes, have a search on here.
I do 700 miles a week in all weathers including snow, that's roughly 35,000 miles a year, and some weekend warrior biker has the nerve to get out of his Audi at work to tell me to I was riding far too fast in the wet (over taking at 50... fast eh?).

I find sitting up on the bump stop, tuck knees and elbows in with chin on the tank is good for a few kph at the end of the straight.
Air follows over the curve of your back & any air caught in your shoulders can escape between you legs.
