That's hilarious!!

Great question! I had ridden the RSV4 a couple of times and I really liked it. There were a couple of reasons I wasn't sold on it tho. Firstly the engine and power.
The V4 is an interesting engine but to me it didn't feel and sound quite right in comparison to the inline four I've always had. Also, pre 2015 and they're down on power up against it's competitors.
The other reason is the size and feel of the Aprilia. It feels small and chuckable, much like the R6.
If I'm totally honest tho, the 'unstable' style of the R6 took a LONG while to get used to and I'm thinking the more planted nature of the BMW might suit my natural style even better.... At least thats what I've currently justified....
Who knows tho. What I do know is that both have an excellent package and either will be a bit of a learning curve.
You're right, It would have been fun to be on the same bike as Marshy, so we're going to see about getting a pillion seat added for the remainder of the season!!
