My Spitfire deflects wind just over my helmet when adjusted high. By high I mean its top edge is just below my line of vision when looking straight ahead. It deflects enough air so that it's a lot more comfy to ride at high speed for a long time. I believe it would also help in staying warm quite a lot in cold weather, and I get plenty of air from underneath it, so that keeps me reasonably cool here in the FL heat.
Because of its shape though, (and I'm 6'2" in that lowered Corbin) while it deflects just over the helmet, there's still quite a bit of turbulence to the sides, which makes for a lot of wind noise.:damn angry: Even with the Schuberth C1 lid and 30dBa foam ear-plugs, I still get some ear ringing after an hour of 75+mph highway riding. There's also still plenty of air pressure on my arms, but I don't mind that much - it makes 100+ speed feel like I'm going somewhere. :eusa_dance:
Because of the noise (I make music for a living) I am interested in something maybe slightly wider, but don't like the looks of those much..:bang head:
I've seen 135 on the speedo in a straight line without any adverse effects,
although I'm quite unhappy with how my bike is currently sprung and handles but am hoping new tires and head bearings and races will help some. It's fine in a straight line line since doing the Furbur fix, but I wouldn't dream of trying to make any kind of turn above 75mph, and it also twitches horribly over every bump or lane change at high speed. I have a feeling the suspension is shot 'cos I've never had a bike where I can feel every pebble on the road like on this one. I was told it has 'progressive springs' front and back when I bought it, but feel I need to service the forks and trash those shorter shocks with no damping adjustment.
As far as keeping your hands warm, forget about windshields - they don't do much about chill factor (I should know I lived and rode in UK for 20 years!).
What I can
really highly recommend though, is
heated grips!
You can get a decent set for about ?30 ($60) on eBay (look in ebay.co.uk) and fit them yourself no problem. The good ones come with an on/off knob that's also a temp control. The last ones I had on my Aprilia Pegaso I could never have higher than the third click (out of 8) or it felt like my gloves were about to melt :angry flame::angry flame::angry flame:
You can't beat having the heat inside your hands in cold weather rides!
