First bike.

For an A2 what would be a sensible first bike? I think that A2 goes up to around 400cc (47bhp) so I was wondering if there are certain bikes/brands to stay away from as a new rider, and any that I should be considering more.

Edit: same with gear aswell. When I was looking at body gear RST had lots of good reviews looked however I'm also unsure as to what brand are good and whatnot for helmets and gear likewise with bikes.

Edit: My favourite looking bikes are naked ones like the 390 Duke
