Do you think Yamaha could use the engine from the FZ-09 for the next gen Viking or maybe a Viking sport model?

For those of you unfamiliar with the FZ-09s engine it is an 847cc three-cylinder featuring even, 120 degree firing intervals, together with unique, unequal length intake funnels. It has four-valve heads and fuel injection, as well as a relatively short stroke (78 mm bore and 59.1 mm stroke) with an 11.5-1 compression ratio. The transmission is a six-speed. Ride-by-wire throttle and Yamaha D-Mode, which allows switching between three throttle-control maps for different performance characteristics...

115 bhp at 10,000 rpm. Peak torque 65 foot/pounds which should arrive at 8,500 rpm...

Full Specs:

Engine type: liquid-cooled

Displacement: 847 cm³

Bore x stroke: 78.0 mm x 59.1 mm

Compression ratio: 11.5 : 1

Maximum power: 84.6 kW (115PS) @ 10,000 rpm

Maximum Torque: 87.5 Nm (8.9 kg-m) @ 8,500 rpm

Lubrication system: Wet sump

Carburetor: Fuel Injection

Clutch Type: Wet

Ignition system: TCI

Starter system:Electric

Transmission system: Constant Mesh

Final transmission: Chain

Based on that do you think the FZ-09s engine could be re purposed into a Viking or another SxS in the Yamaha pipeline?

Probably not, too big to package in there... the FZ-09 engine likely has a bit in common with the triple cylinder engine Yamaha uses in their Nytro and Vector snowmobiles. I've owned/played with those a bit, always thought it would make a nice sxs engine swap.

My guesses... we will see a V-twin, probably all new. There's plenty of room for it. If not that, then a variant of the inline twin that comes in the Super Tenere XT1200. It's little brother, the XT660Z (not sold in US), essentially has the same single cylinder engine as the Viking/Rhino/Grizzly/Raptor Series.
