KLX140R against the small trail bikes

At $3,799 it costs $200 more than Honda's CRF125F at $3,599 and $150 more than Suzuki's DR-Z125L at $3,649. It has about 20cc more engine than those two and weighs 205 lb against 194 and 196 lb. Yamaha's TT-R230 is $4,699 at 251 lb, and Honda's CRF300F is $5,099 at 271 lb.

The KLX140R is the one to consider for a teenager or small adult who will outgrow a 125.

Fit and growth

The KLX140R has a 30.7 in seat, 9.3 in of ground clearance and a 205 lb curb weight (191.7 lb dry), which suits a smaller adult or a teenager. The 33 mm fork and 7.1 in of travel are enough for casual trails, and the five-way preload adjustment on the shock lets you set it to the rider's weight. A rider who keeps growing will outgrow it.

The step up is the KLX300 at 35.2 in and 302 lb, or Yamaha's TT-R230 at $4,699 and 251 lb. A carburetor rather than fuel injection keeps the maintenance simple but means jetting needs attention if you ride at altitude.

KLX140R against the CRF125F and DR-Z125L

Honda's CRF125F and Suzuki's DR-Z125L are the closest trail bikes, both slightly smaller.

It gives the low 30.7-in seat and 7.1 in of front and rear travel, and calls the broad, smooth, high-revving 144cc engine, with a manual clutch and five-speed transmission, an efficient and user-friendly package.
