Yep. the mounting is dirctly onto the sub-frame, 2 x 10mm bolts. I'd say it's at least as hot as a cup of tea made with boiling water, a minute for the T-bag to infuse flavour, and stick your finger in. Whoops..take it out!
When I say hot, I mean hot. You couldn't hold it for too long, else you'd get heat blisters I think. The brain says it's hot, let go!
Since the wiring harness backs onto it on the two 'bendable' straps, can't be healthy for the wiring....? If an original Road plastic seat was used, it would begin to melt it I'm sure. The RGV rectifier gets a littte warm, nothing like this though.....?
