There is a lightweight Tuareg set you can get, well vented and reasonably cheap.......

I use the jacket for trail riding and it has two frontal flaps and most of the back opens up. the sleeves are vented all the way from top-to-bottom too.

I think the pants have zip off bottoms.

I wouldn't want to come of the bike at any speed though!
