My bike's given me lots of shit with wiring, batteries, bearings, etc. All fixed under warranty though and since fine. I believe most of it to be factory faults though. Other than that I had a problem with a Bantam once which caused a bit of damage to my bike! Also fixed now...
Why not tell everyone of every problem I've had? Well, because no one asked and I really don't think everyone is interested! Plus I am not planning to sell any of my bikes so I’m not deceiving anybody…
