forget BEC, get a rotary in there
I think you'd have more fun if you kept it in its intended chassis, ie. on two wheels. 
It'd go round corners much much quicker with four wheels though.
The engine looks to be quite tall though and the specs aren't really that special. It may be Aprilias most powerful bike engine ever but I
get the feeling they're playing catch-up to the Japs (power wise). It is however a nice compact and balanced engine and more suited to two wheels
than four IMHO.

Quite a few interesting engines making an appearance soon(ish).
New GSXR10000K9 looks rather nice (new, compact, short stroke). Odd V5. a few V4's and (this'll be interesting) BMW's new WSB
orientated lump.
Should be a good year when these work their way through the system.
Me, well, I'm hoping the new GSXR1000 will scream like the specs say (14K limit). Not far off the 'old' 750:

Other (less useful) derivatives that at least raise a giggle when I look at them are the new V-Max and Rocket developments.
