  • 2018 Honda NM4

The Honda NM4 is a touring motorcycle with “futuristic” dimensions. The machine is powered by a 670cc parallel-twin, a sophomoric powerplant tuned for relaxed riding and not hard-core hammering. Honda’s six-speed dual-clutch gearbox allows fully automatic or electronic “manumatic” shifting via handlebar-mounted paddles. The Honda NM4 is as radical as radical gets in street bike styling and absolutely an extremely bold design overlaying proven engineering.

About the 2018 Honda NM4

As sporty looking as the NM4 is, the cruise-tastic rider triangle puts the rider deep into windsock territory with an upright back and feet well forward. The liquid-cooled, parallel-twin actually runs with a 73 mm bore and 80 mm stroke that leaves it a smidgen under-square. Compression is reasonable at 10.7:1, and a SOHC times the eight-valve head.

The bones set the tone with a long and low build that leaves us with a 64.7-inch wheelbase and 25.6-inch seat height. The steering head layout gives us 33 degrees of rake and 4.3 inches of trail for a ride that trends more toward the stable.

Suspension components are something of a yawn with standard, fixed-parameter forks up front and a Pro-Link mono-shock in the back with 3.9 inches of travel all around.  This is definitely sufficient for street work, it ain’t a dual-sport after all, but the lack of tune-ability in the suspension cuts into the NM4’s versatility and comfort on long trips.

The NM4 rolled for a base MSRP of $10,999 in 2016 but comes back in 2018 for $11,299. You can get it in any color you want as long as you fancy Matte Black Metallic. The NM4 comes with Honda’s one-year, unlimited-mileage warranty.
