doesn't answer your question but these from ultimate add ons are very good imo, hot, and have an oem appearance
In the tradition of UKGSer and the internet in general. I suggest different ones from Daytona (Japanese not German boot maker)

They have the reputation of making the best ones for decades, with their original ones being analogue and favoured by dispatch riders in the 1990s.
They also do a 130mm on the sbs website. - innvis ones - doh ultimateLooks pretty neat .
Think they might be a bit short at 120mm.
Will measure OE grips tomorrow.

Think they might be a bit short at 120mm.




they are hollow ended to accommodate bar ends
you also need a small gap between the bar end and grip to allow for expansion, otherwise the throttle can stick! This used to happen on my R1150GS with BMW heated grips until I learnt to slacken off the bar end periodically as it seemed to tighten itself.
just looked, the Oxford Evo are also 120mm, trimmable to 110mm
Odd as they were on my Himmy 450 and the dealer fitted them, and as far as Im aware thats ride by wire, but probably best to swerve if any doubt.


The button on the UAs is much bigger than that on the OxfordsI’ve just bought similar grips for the pricely sum of £90. I had a chat about the new model with the suppliers and the guy I spoke suggested I stick with the ones you’ve bought. He said they’d stocked the Daytona ones in the past and the failure rate was too high. Hence the recommendation to hold off on buying Oxford’s new offering to see if they had the same issue.
Micky makes a good point. Operating the new ones with cold fat fingers ill not be easy.
