Yes, another thread about TUBES! Where are you guys sourcing your 150/70-17 or 140/80-17 tubes for the rear of the GS from?
apologies, I am in the USofA. would like interweb-based vendors in the US to lessen the shipping charges.
I use these: http://www.motorcycle-superstore.com/1/4/77/29963/ITEM/Michelin-TR-4-Inner-Tube.aspx?WT.ac=SLIsearch They came on my bike.
front https://www.denniskirk.com/irc/heavy-duty-21-in-inner-tube.p535160.prd/535160.sku rear (i think - always had a more difficult time with the 150/70-17 in an HD). https://www.denniskirk.com/irc/heavy-duty-17-in-inner-tube.p535165.prd/535165.sku in a jam you can stuff an 18" tube in the rear.
