I've used them on my 1150 GSA the last couple of winters and still got them on just now.
They're alot better than TKC's off road and they don't get clogged up in the mud.On the road the're noisey ear plugs a must.They grip really good in the dry you can scrape the pegs.I'm the wet they're pretty good much the same as TKC's.The ones on my bike last really well the fronts now done 2 winters probably 6000 miles still a bit of life in it, put a new back on last October done 3000ish alot of it offroad getting abused think i'll get one more run out of it.Done a few weekends away with the bike loaded cruising at 80/90 mph and they don't wear much.Can't complain at the price either
