I picked up a "new" bike this afternoon.
It's a '94 Honda Magna 250, a JDM grey import (marketed as the VT250C in Australia), with 32,000 km on the clock.
The previous owner claimed an average 250 km from the fairly small 8 litre main tank, about 3.2 l/100 km.
I hope I can do better than that.
I'll give it a bit of TLC first, then run through a couple of tanks to set a base line before I start some planned mods.
