125SX requires a busy clutch hand and never letting off
the throttle. Failing to do so will cause the engine to bog.
( 3) Husqvarna TC125. The TC125 mirrors the KTM
125SX at top speed, but it suffers in the midrange thanks
to the clogged airbox. Some testers actually preferred the
tamped power spread of the Husky over the KTM, but
most riders liked the explosiveness of the 125SX. Having

it only shines in one area—top-end power.
WHICH BIKE HAS THE BEST SUSPENSION?
(1) Yamaha YZ125. There is no contest. The Yamaha
YZ125, with its Kayaba Speed Sensitive Suspension
(SSS), is the best in the business. What amazes the MXA

with a progressive and consistent ramping-up effect.
Bottoming resistance is amazing. Simply put, the YZ125
suspension is magical.

right leg controls the rebound damping. There are four
separate chambers that contain different parts. Chamber
1: main spring and air chamber. Chamber 2: cartridge
and sealed chamber full of oil. Chamber 3: housed inside
Chamber 2, it is where damping is created. Chamber 4:
extension reservoir chamber. What does this all equate
