472cc CHEETAH SUPERCUB YAMAHA BANSHEE / RZ COMPLETE ENGINE + PARTS KIT

BRAND NEW • ZERO RUNTIME • $13,196 DOCUMENTED BUILD RECEIPTS• PROFESSIONALLY BUILT- COST TO DUPLICATE IS NOW WELL OVER $15,000.00

If you're looking for one of the most extreme two-stroke engines we've ever had on the bench here at Kaplan Cycles, feast your eyes on this incredible 472cc Cheetah Supercub complete performance engine package.

This is not a rebuilt used Banshee motor and it is certainly not your average big-bore engine.

This engine was professionally assembled from the cases up using brand-new components, with more than $13,196 invested in the complete build and parts package in February 2023. We have approximately four pages of receipts documenting the build, and copies will be included with the sale.

The owner originally commissioned this engine for a high-end, frame-off-restored Yamaha Banshee but ultimately did not install it. His Loss Your Gain;

BRAND NEW — ZERO RUNTIME

The engine has never been installed and has never been started since assembly.

There are no used engine cases, no old transmission being reused, and no mystery internal components. This was built from the beginning as a serious, premium-performance engine using new Yamaha OEM components and some of the best aftermarket parts available.

472cc CHEETAH SUPERCUB ENGINE

At the heart of the package is a CPI Cheetah Supercub 472cc combination featuring:

• 72mm plated Cheetah Supercub cylinder

• Custom 72mm Wiseco Race Choice pistons

• 4mm stroker crankshaft

• Stage 4 cylinder porting

• Engine cases bored and ported to match

• Polished cylinder

• Billet Supercub cylinder head

• 30cc domes

• Max-Loc head studs

• Extensive titanium hardware

This is a serious, professionally assembled high-performance two-stroke package designed for someone who wants considerably more than a conventional Banshee engine.

BRAND-NEW ENGINE CASES & INTERNAL COMPONENTS

The build goes far beyond simply installing a big-bore top end.

This package received brand-new Yamaha engine cases, along with an extensive list of new internal components including:

• Complete new transmission

• Modified shift cam

• Modified shift shaft

• Upgraded bearings and seals

• Extensive new Yamaha OEM internal components

• Billet water-pump impeller

• Premium hardware throughout

Everything was designed and assembled as a complete system rather than pieced together from miscellaneous used components.

HINSON 7-PLATE CLUTCH & LOCK-UP SYSTEM

Handling the power is a serious clutch package featuring:

• Hinson seven-plate clutch

• Lock-up clutch system

• Polished Modquad lock-up clutch cover

• Billet lock-up components

• Chrome shifter

• Polished Billet kickstarter

The polished aluminum, billet components and chrome hardware make this engine just as impressive visually as it is mechanically.

It truly looks like a piece of mechanical artwork.

GENUINE KEIHIN PWK CARBURETORS

Fueling is handled by a brand-new pair of genuine Keihin 35mm PWK carburetors feeding through a premium intake system consisting of:

• Dual genuine Keihin 35mm PWK carburetors

• One-piece billet intake manifold

• V-Force 4 reed system

• Dual Superflow air filters

• Filter covers

• Braided throttle cable

• Fuel-line kit

• Silicone hoses

The carburetors and related components are brand new and included with the package.

OEM YAMAHA IGNITION

Rather than cutting corners on the electrical system, the engine was built with genuine Yamaha ignition components including:

• OEM Yamaha stator

• OEM Yamaha flywheel

MATCHED SHEARER PERFORMANCE EXHAUST SYSTEM

Also included is the performance exhaust system selected specifically to complement this engine combination.

The package includes the chrome Shearer Performance pipes, along with the associated:

• Pipe springs

• Mounting hardware

• Exhaust hardware

This means you're not buying only a bare engine and then spending thousands more trying to source the intake, carbs, exhaust and supporting components necessary to complete the build.

The major pieces are already here.

OVER $15,000 REPLACEMENT COST AND MONTHS WAITING

The documented total for this engine package was approximately:

$13,196 in February 2023

And that was more than three years ago.

IT HAS BEEN STORED IN HIS HOUSE WRAPPED IN BLANKETS IN A COOLER SINCE BUILT

IT IS BRAND NEW, PERFECT AND SPOTLESS

Considering the increased cost of INFLATION on components, machine work, labor and shipping, duplicating this exact specification today could reasonably cost considerably more.

There are less-expensive Supercub packages available, but they begin with a 2 existing used Banshee engine and reuse portions of that engine.

That is fundamentally different from this package.

This engine was built using brand-new cases, new transmission components, new internal components, premium aftermarket hardware and an extensive list of upgrades.

SERIOUS HORSEPOWER POTENTIAL

Similar 472cc Supercub combinations are commonly built as extremely high-output engines. Depending on porting, fuel, compression, ignition setup, exhaust, carburetion, tuning and final configuration, comparable combinations have been reported in approximately the 90–100+ rear-wheel-horsepower range.

We are not representing this particular engine as having produced a specific horsepower number, because this engine has zero runtime and has not been dyno-tested since assembly.

The final output will depend heavily on the installation and tuning.

What we can tell you is that the parts combination speaks for itself.

PERFECT FOR A HIGH-END BUILD

There are countless possibilities for this engine.

Install it in a serious:

Yamaha Banshee

Build an outrageous:

Dune / Sand Machine

Create a:

Drag Banshee

Or take it completely outside the box and build an incredible:

Yamaha RZ350 / RZ-Based Street or Road-Race Machine

Imagine this polished 472cc Supercub engine sitting inside a high-end polished aluminum chassis.

For the right builder, the possibilities are nearly endless.

NO WAITING MONTHS FOR AN ENGINE BUILD

One of the biggest advantages here is that the hard work has already been done.

You don't have to source dozens of individual parts, send cases and cylinders out for machining, wait for porting, collect the transmission and clutch components, find carburetors, source the correct exhaust and then wait months for the engine to be assembled.

This one is built.

The engine has:

Zero runtime.

The parts are here.

The receipts are here.

The machine work is done.

The polished components are done.

The engine is assembled.

The complete supporting package is ready for its next owner.

WHY THIS ENGINE IS SPECIAL

This is the type of engine enthusiasts can spend years planning and piecing together:

472cc displacement.
4mm stroker crank.
72mm Cheetah Supercub cylinder.
Stage 4 porting.
Port-matched cases.
Billet head.
Hinson clutch.
Lock-up clutch.
Genuine Keihin PWKs.
V-Force reeds.
Shearer pipes.
OEM Yamaha electronics.
Billet components.
Titanium hardware.
Extensive polishing.
All-new engine foundation.
Zero runtime.
Documented professional build.

If you're building a serious Banshee, RZ project, race machine, dune bike or show-quality two-stroke and don't want to compromise on the powerplant, this deserves a very close look.

It's brand spanking new, it's never been installed in the machine it was intended for, and the build quality is exceptional.

Call Kaplan Cycles with any questions regarding the engine, components, documentation, shipping or purchase arrangements.

Thanks for looking, and God bless America.
