Teknic seems to be very popular with alot of racers out here. I myself also own a Dainese suit, and I would say go with one of them if you can afford it. But for the money Teknic is a great suit also (so i hear)
ive got a teknic suit aswell i crashed at grattan last lap turn one end of the front straight at ehhh 100 to 130mph, got up walked away no holes, no broken seams, just bruising, and a heat burn from the friction on my leathers. for me a great suit, ohh and is a 2 piece aswell. i have to now bring it in for some repairs but its lasted since 96
I picked up a Violator, almost went with the xcelerator but figured the money would be better spent on tires than roo. When it comes in I'll post up my thoughts. I have no affiliation with these guys but fwiw, sportbiketrackgear is very pro teknic. check out their site for some videos.
I have a Teknic Violator one piece suite and I love the thing. Here is my opinion on the whole thing. I have a buddy that is racing WERA and he had his suit custom made by a guy out in Crazy Land...AKA California. He threw down 3k for the whole deal. I spent 350 on ebay from a guy that never wore the thing because he was to fat to get in it. I like my better and when I crash I will throw it away and buy a new one. Up to this point very happy.
