Loaner Bikes

My hubby, Dave, bought a BMW R65LS from a well known BMW dealer as a cheap commuter while he repaired his regular ride that had been T-boned by a texting woman. The R65LS had been the dealer's loan bike. It handled badly so he checked it over when he got home and found one rear shock absorber had a bent damping rod and the front forks had different springs in each leg. One was standard and the other was progressive plus they were 40mm different in length. After the shock and springs were fixed the LS was such a delight to ride we ended up keeping it.
Dave was also given a Virago 250 as a loaner. It gave him a sore back and he couldn't wait to give it back.

Bmw was obviously a trade in they didn't check out before using it as a loaner

You are all lucky. There are no loan bikes down our way. You are lucky if they offer you a test ride to be honest. That's part of the reason I do all my own servicing and even change my own tyres.
