| Avoid I reckon - this would be such a liability.
I reckon you're doing the right thing with a start to racing with the DD series. See how this goes this season and take a view later in the year.
Even then, there are much cheaper ways to go racing than getting a RS - wise words from Felix.
Maybe Supertwins is the next step up from DD if you fancy that? There are the 400cc series too.
IMHO, if you're serious about racing then I reckon you should be concentrating your efforts and cash on the racing and not on the maintenance side of things. An RS may be too much of a distraction - would be a great bike to ride though!!!
Good luck
