Yep, that's the fun of having a 2nd bike, they must be totally different in every way.
The Thruxton R does feel small, light and agile - and the riding position is very different being a cafe racer. Its also brilliant for commuting in clogged up London. Goes through gaps I couldn't attempt on the Multi.
Absolutely love both bikes though. and feel very lucky to have 2 fabulous bikes in the garage.
