Did you expect KTM to release a new 125
two-stroke? Neither did we. The 2016
125SX has a motor that is said to be 4. 4

to be increased. The 125/150 frame
got attention in the same areas as
the four-stroke frame—stiffer in side-to-side flex and more compliant up
and down. The power valve is still
mechanical, and the intake is still
through case reeds.
The larger two-strokes have fewer
changes. The 250SX, 250XC and
300XC have unchanged motors, but
they did get the new top triple clamp
with rubber-mounted bars, lighter
wheels and Galfer brake rotors. The
XC-W line and the EXC dual-sport
bikes will be announced soon, so
keep an eye on www.dirtbike
The KTM 150SX is virtually the same bike
as the 125, but with a 4mm-larger bore
and 0.4mm-longer stroke.
