I went from having a small fairing and windshield on my 125 (Honda Varadero 125) to a naked GSX 1400. No fairing, no windshield - just me and the elements.
What amazes me the most is the effect that my gear has on the wind (or is tht the other way around?) I have three jackets - all with protectors:
My ISX jacket is great - all weather, waterproof and is comfortable at speeds up to 85 mph.
My mesh jacket is not waterproof (but great for warm days) and also does not cause any problems at speed.
My Akuma jacket is also all weather, but causes a definite upward pressure on my helmet when I'm doing above 75mph. I used to think that it was my helmet, that's one reason why I bought a new one when I picked up the new bike. Now I have narrowed it down to the Akuma jacket ... wierd, huh?
