Stage6 50cc Aluminium Cylinder Kit - Minarelli
Horizontal L
C


Minarelli horizontal LC
10mm piston pin

The 50cc cylinder from Stage6 offers you the
possibility to achieve a higher power output without
increasing the displacement. The cylinder is made of
aluminium and equipped with a bridged exhaust port.
It is one of the most powerful cylinders in the class
with 40mm bore. Its strong points include good
acceleration and heat dissipation, long lifetime and
excellent ability to build RPMs. The kit comes
complete with head, piston and gaskets.

Stage6 Modular Racing 70cc Cylinder - Minarelli
Horizontal LC


Minarelli horizontal LC
70cc modular racing

The 70cc liquid cooled racing version of the Stage6
cylinder kit with a two-part cylinder head. This is a
high quality aluminium cylinder in the upper mid-race
range. Like all Stage6 aluminium cylinders, the racing
versions is also manufactured with a special durable
Nikasil coated liner. What differentiates this cylinder
from the basic racing cylinder is the modular racing
version comes with a two-part cylinder head, which
offers better heat dissipation. A 17.5mm carburettor is
highly recommended and even better, a 19mm carb.
When this cylinder is used in combination with the
Stage6 R1200 / R1400 exhausts, Polini ForRace or
Carrera 16 from Yasuni, you will achieve exceptional
power. The cylinder is supplied with a coated Asso
piston, carbon reeds and 5 base gaskets (0.10, 0.20,
0.30, 0.40, 0.50) to adjust port timing and squish.

Attention: Kit ships with a universal gasket set. Please
make sure to use the black, thicker o-ring between
inner and outer cylinder head. Do not use the red one.

Stage6 70cc Racing Cylinder Kit (10mm) -
Minarelli Horizontal LC


Minarelli horizontal LC
10mm piston pin

The racing version of the Stage6 cylinder line. This is
a high quality aluminium cylinder with power among
the best in the mid-race range. A very durable nikasil-
coated liner together with the fast heat-dissipation
nature of aluminium, ensures excellent reliability. The
main differences to the Sport Pro are longer port
durations, a bridged exhaust port which makes for
huge port time area and a higher compression ratio.
This cylinder needs either a 17.5mm or even 19mm
carb. Together with the proper exhaust, this kit will
yield excellent performance. Delivered with a specially
coated Asso piston, a set of carbon reeds and a variety
of base gaskets to adjust squish clearance.

Stage6 Sport Pro 70cc Cylinder Kit - Minarelli
Horizontal LC


Minarelli Horizontal LC

You can get this Stage6 Sport Pro 70cc plated
aluminium cylinder, for the same amount of money
that usually only gets you a humble cast iron cylinder.
A comparatively tame exhaust port timing together
with a huge port area make for an extremely torquey
kit which also revs nicely. There are not many
cylinders powerful enough to compete with the Pro's
pace of the line. With the known thermal advantages
of aluminium cylinders, you get a reliable cylinder with
a strong asso piston, a set of carbon reeds and a
choice of base gaskets to adjust squish clearance.

10mm wrist pin

A great modular cylinder kit from the Metrakit
range of ATV / quad products. The cylinder is
composed of a special aluminium alloy and the inner
re-covering is made of a nickel and silicone-carbon
compound. The Metrakit ProRace offers well
shaped transfers and a coated Mahle piston with
one ring. Peak power at around 13,000 rpm,
depending on gearing and exhaust. This cylinder kit
features a modular cylinder head like the ones from
the MHR Team or Polini Evolution. It is necessary
to use a long-thread spark plug with thermal
characteristics similar to B10EGV. This high-end
tuning product works well with the Metrakit water
pump kit.

Stage6 Crank Bearings (Polymer Cage) - Minarelli


Trying to save money by using low-quality crankshaft
bearings with highly tuned engines is not a good idea.
That's why Stage6 collaborates exclusively with the
leading European and Japanese manufacturers of
bearings and radial shaft seals such as SKF and
Corteco. Stage6 offers you HQ crankshaft bearing kits
in 2 versions: a metal ball cage or a polymer ball cage.
According to SKF both versions can rotate up to
20,000 rpm and have of course a higher bearing
clearance (C4). Sufficient lubrication and proper
installation of crankshaft and bearings are of course
essential for long life. The version offered here comes
with a polymer plastic cage which has higher elasticity
and a reduced friction coefficient as compared to the
metal ball cage. This is the type of bearing
recommended for racing engines. What is also
important is the correct ignition, timing and
carburettor settings because bearings should not be
subjected to more than 120 degrees for a longer time
in order to prevent damage. This is also the reason
why the TN9 bearings should not be used in engines
with catalytic converters. Please keep in mind that the
half-open cage must be inserted so that it faces the
crank webs.
