The MAX-12XZ has been developed
to satisfy the power demand of all the
1/10 touring car enthusiasts from expert
to sportsman drivers. This is not a
superficial model change... most
of the major parts have been newly
designed for improved performance to
cope with the ever-evolving changes
in chassis design. A new material
has been used for the connecting rod
for increased durability and the
crankcase has been ‘beefed up’
for increased rigidity.
Ever wanted fewer pit stops during
a race to extend your lead over your
competitor? The O.S. 19XZ-B Speed
offers 10% better fuel economy
over the current 21XZ-B Speed, but
with the 21J2 carburettor and 6mm
carburettor reducer it still has all
the performance you need to win.
The 19XZ-B Speed also has a DLC
(Diamond Like Coating) coated
crankshaft and ceramic bearings to
reduce rolling resistance.

Think of it as a 21XZ-R Version II on
performance-enhancers. It
offers the same fuel-stretching
time advantage, but even more
aggressive timing for added
horsepower and the fastest
lap times you've ever turned.
It wowed the crowd at the 1/8 Scale
On-Road Worlds in Miami, Florida,
when team drivers turned in 4th &
5th place finishes with production
models.
The 21XZ-R Version II’s
aggressive timing puts explosive
acceleration and top-end speed
at your fingertips, while surprising
starting ease lets you unleash
its race-winning potential right
out of the box. The 21M carb is
unmatched for smooth, linear
acceleration, too. Performance
tuning options include a carb
restrictor as well as four
adjustable settings.
