SV650…
Yep - it’s a vee - but not an SV.
To give you a clue - it’s a sporty production bike from a low volume manufacturer.
It’s very rare - although I did see two together parked up in Brighton on an Ace/London to Brighton ride a few years back.
MV Augusta? Is my guess.
Are they twin?
I keep being drawn towards Moto Morini.
French VOXAN
A Guzzi ?
C.J. is the winner! 
Well done sir! Very difficult one. 
Voxan is a French motorcycle manufacturer established in Issoire, France, in 1995.
Originally initiated by Jacques Gardette, the project involved different partners, including Alain Chevallier, who designed the chassis part, and société Sodemo, established in Magny-Cours, France, who designed the engine. The first prototype was delivered in 1997.
The first 50 Roadster models were delivered in 1999 to dealerships. The Café Racer models were added to the lineup in 2000, and the Scrambler model was released in 2001.
Although well considered on the French market, Voxan had a hard time competing against better established Japanese and Italian manufacturers.
In June 2002, Didier Cazeaux and Société de Développement et de Participation bought Voxan to ensure its continuity and, in April 2003, the manufacturer started producing its motorcycles again.
The Street Scrambler model was released in 2003, and the Nouveau Scrambler and Black Magic models in 2004.
All Voxan motorcycles use the same engine, which is unique in its design. This engine is a V-Twin with a 72° angle and 996cc of displacement.
That is one ugly motorbike. No wonder they’re struggling against the big boys 
it looks better in the flesh/metal
