I don't have a GS... i would if i could afford one though, i have a V-Strom DL1000.
I am a member of xrv.org.uk and was pointed to this site for Val.H muffs and i liked it so paid the subs, well worth it as i got a Shoei Multitec off Ash for £110 and it was mint condition.
I didnt see your bike until i was on the way out and thats when i realised you were probably a member on here. The tosser sticker kind of gave it way
Ride safe...
