At the heart of every KRASH ‘Ready To Perform’ craft is our powerful,
proprietary 997cc twin-cylinder 2-stroke engine, the KV997.
The power-valve cylinder is constructed of A365 high-pressure cast
aluminum and features 88mm cast iron sleeves. Wiseco forged pistons
are driven by our 82mm stroke forged crankshaft fitted with
ProX connecting rods. Prior to assembling the crankshaft, all pins and
surfaces are nitrate treated for increased durability. Tunable wet
exhaust system features oversized stainless steel expansion
chamber and aluminum water box. Premium pre-mixed fuel is delivered by
our dual 48mm ‘Black Ops’ carburetors, featuring Mikuni internals,
through high-performance carbon fiber reeds. Combustion is controlled
by our DC-CDI that is programmed with three preset maps that can take
you from 70hp to 100hp to 130hp at the push of a button.

CYLINDER
The KV997 Cylinder is made from A356 high pressure die cast aluminium
and 88mm bored steel sleeves. It features 4 Auxiliary ports, 1 boost
port, 2 Auxiliary exhaust ports and 1 main exhaust port per cylinder.
The air and fuel are feed into the intake through the side of the
cylinder at a 30 degree angle and wrap around the crank as the piston
plunges from TDC to BDC. The cylinders are 150mm apart to increase the
inner auxiliary ports area for improved bottom end punch.
CRANKSHAFT
The 4340 forged crankshaft weighs in at 7.8kg and gives the motor an
82mm stroke while being assembled using NSK C3 bearings.
Our rods are 144mm long giving our engine an ideal rod to stroke ratio
of 1.76. All pins and surfaces are nitrate treated for increased
longevity.
