Hyosung Scooter

Hyosung Motors expands its two-wheeled lineup in 2010 with the new ST7 cruiser, alongside its 650cc and now fuel-injected 250 motorcycle lineup. However, the South Korean-based manufacturer also delivers a scooter lineup for American commuters, featuring a lone 250cc model in the MS3-250, as well as a trio of 50cc 2-strokes.

Hyosung MS3-250

The largest of the Hyosung scooters, the MS3-250 gets its power from a liquid-cooled 4-valve Single. The 73 x 59.6mm bore and stroke work out to a 249cc displacement, with Hyosung claiming peak numbers of 25 hp and 16.4 lb-ft torque from the fuel-injected design. The manufacturer claims its 250’s power transferred via CVT makes the MS3 freeway capable.

The MS3-250 rolls on 13-inch front and 14-inch rear wheels, with a telescopic fork and double rear shocks making up the suspension components. Stopping power up front comes courtesy of double disc brakes, the 240mm rotors pinched by two-piston calipers. A 220mm single disc/2-piston caliper takes care of things out back. Riders sit from a 29.5-inch seat height to wield the 341-lb scooter (claimed dry weight).

Other perks for the MS design include LED taillights and a decent looking LCD instrument console, which includes analog speedo and tach, as well as digital fuel and temperature gauges. The MS3-250 retails for $4499 and comes with a two-year warranty.

Hyosung 50cc Scooters

Hyosung’s three little 50’s – the Prima, Rally and Sense – are all powered by an air-cooled 49cc 2-stroke. The carbureted engine features 5 hp and 2.8 lb-ft power claims, turning its rear wheels via the standard scooter CVT. All feature a small telescopic fork and preload adjustable rear shock. Meanwhile, a single 162mm disc/single-piston caliper front and rear drum make up the braking components. While no MPG claims are listed, the fuel-sipping 2-stroke should get near or above a 100-mile range from its 1.25-gallon tank.

Tweaks in bodywork and tires make up the change in models. Most expensive of the three is the $1899 SF50R Rally, which claims its headlight guard and fat 120 and 130 10-inch tire make it “as confident off road as it is on.” The $1799 Prima model rolls on 12-inch wheels, with the SD50 smaller 10-inch treads and a $1599 MSRP. All the Hyosung 50s come with a one-year warranty.
