x's 2 on the chain over shaft on the Tiger. Aside from the weight savings, I can carry an extra chain in my saddle bag, I can't carry a spare shaft......and though I will get hate mail from GS owners SHAFTS DO BREAK, and usually in the middle of nowhere.
Been riding 30 + years and with proper mtc. have never broke a chain. But if I am riding the Road of Bones, or through South America or some such, give me a chain and a spare over a shaft any day.
I saw a subliminal advertising executive, but only for a second.
