There's been a lot of discussion today (April 1st, 2009) about the relative merits of the Buell motor compared with the SV1000; the main concern with the Buell is the width of the primary and possibly cooling problems when it's faired.
The SV1000's only real problem is its length, though I am not too concerned about wheelbase; I'm sure it will still be shorter than a Quasar and by all accounts they go round corners very well.

So I thought I would post a few pics from back when I was designing the R1-based machine.

Been thinking about the Buell 1200 as a sutible engine for my FF, what it has going for it,
Very narrow,45deg V so short to, side exit exhaust so no problems with a hot crotch (eg a sv1000) enough horse power 95-104bhp, but much more importantly low reving low down torque, IMHO this is esential for real world riding ie power availble instantly.
It also has very respectable economy ive seen 55mpg quoted.
