|The Royal Enfield Bullet looks great a with modern parallel twin motor.|
Well, ask the man who built one. In this case I don't mean Aniket Vardhan, who combined two Royal Enfield singles to build his V-Twin Musket.
Let's ask John Dawes, a Brit who lives in Spain and whose "Trifield" is featured in Sump Magazine.
It's a Royal Enfield motorcycle with a parallel twin Triumph Speedmaster motor. That's 865cc (60 horsepower!) in a finished and fueled motorcycle that weighs 100 pounds less than the Triumph.
The Speedmaster's unusual 270-degree crank positions its parallel pistons in such a way that they produce a lopping pattern of power pulses akin to those of a V-twin.
"It's a blast to ride," John commented recently on my item asking what kind of twin Royal Enfield should build.
"I say definitely a parallel twin with an offset crank is best; then you can draw on Enfield's history and keep the V-twin guys happy too!" he wrote.
