I've had the exact ST4 for 2 years now ... apart from the clutch noise I can't fault it. It made our 2k mile 6 Countries in 6 days road trip across Europe easy work 👍
I am sorry but the gas / fuel tank is more like a chisel, towards the rider, so don't jump on from the back, like they did on horses, in the old westerns, or sprano you will sing, guys only, women would never do such a thing.
