I don't know about the "Speed Triple" version, but there was a recent review of waterproofs in RiDE, and they slated Triumph's Chevron one piece suit. The best buy was the HELD AQUA trousers and MISTRAL jacket, and at £35 for the pair it was the cheapest on test. I am after a set, but it has to be blue (fastest colour) and the hunt is still on.
If you are interested, there is a good stockist online at...
Get Geared - HELD Aqua Trousers
Get Geared - HELD Mistral Jacket
Please ask for the Blue jJacket.... they may eventually stock it!!! :-D
