Under straightforward circumstances I can just about manage. The foot clutch makes life very difficult. In combination with less than 20bhp (and no suspension) means that keeping it going in third is a struggle - by the time you've got it into third you tend to have lost so much momentum that you need second again. Not to mention the manual control of ignition advance/retard
And the brakes are virtually non-existent, but I've got a modern Harley too, so I'm used to that.
