The Motrax grips were easy to fit and not too cumbersome. They increase the diameter of the bars by a little, but it's barely noticeable:
The grips come with a controller which allows two heat settings. One press of the button gives full heat (the red LED on the right) and another press gives half heat (the green LED on the left). Pressing a third time turns them off. Full heat was warm, no more than that, and I never used half heat, but it made a big difference to general comfort and control. (By contrast, the heated grips on the Honda had four settings, and anything above two was like gripping a Fukushima fuel rod.) In all, feeble but better then nothing. Mounting the controller on the Renthal bars was a challenge, because the brace got in the way, but I managed something that worked:
The Yamahaha's electrics aren't the strongest at the best of times, and I was concerned that using the grips (and in winter the lights would be on too) would test the charging system to the limit, but in fact they only draw a couple of amps and there was never a problem. A couple of weeks ago, they stopped working. A little investigation revealed that the controller was at fault: with the ignition on (they are wired to a switched live on the igniter box) the red LED was flickering and the box was buzzing like there was a wasp in there. I took it off and dismantled it, but there was nothing in there but a circuit board and two miniature square boxes that might have been relays. 'No User-Serviceable Parts Inside'. I put it all back, to find that it was working fine.
This often happens.
I emailed Motrax in case they were able to supply a new controller, and got this reply:
Dear Sir,Oh dear. Motrax is no more. Purveyors of miniature indicators and aftermarket tat to the discerning sportsbike owner, their catalogue provided many hours of harmless fun while attending to other matters in the smallest room.
Thank you for your email.
We are affraid that MOTRAX no longer exsists as a brand. Oxford bought the name, however it will not be distributed. This means that there is no longer a warranty on the MOTRAX products.
As a gesture of good will, if you would like to return the hotgrips to us, we would offer you some Oxford Hotgrips at 50% of the RRP.
We are sorry for any inconvinience caused by this.

It's a shame, but not a disaster. I won't be taking them up on the offer of a pair of Hotgrips, as the present ones are pretty much Araldited to the bars, and I only wanted a new switch, so removing and replacing them would be a little 'inconvinient', and returning them impossible. But since they have worked faultlessly for the last week, I think I will just leave them as they are. Sumer is icumen in, lhude sing the race cans, and I won't be needing them for a few months. If and when I ever get round to renovating and refurbishing the XT, new bars in a slightly less garish shade are a top priority, so I think I will cross that bridge when I come to it.
