– 2006 Yamaha TT-R50

The latest edition to the TT-R family is the YZ inspired 49.5cc electric start TT-R50.

Now you can look and feel just like one of the Yamaha factory stars with the new TT-R50. Ready to ease the new rider into the fun and exciting world of motorcycling, the smallest member of the TT-R clan sports electric starting and an easy to use 3-speed transmission with an automatic clutch. Watch out, the smiles will be contagious.

Engine:

Air-cooled, 49.5cc, SOHC, 2-valve, 4-stroke powerplant produces smooth, reliable novice friendly power that eases the new rider up the learning curve.

Convenient, push-button electric starting makes starting a snap and takes one of the hassles out of earning to ride.

Newly designed compact engine cases keep the engine narrow, making it easier for a smaller rider to get their feet firmly on the ground.

All new lightweight crankshaft design means crisp throttle response. The piston and camshaft are also new designs.

The cylinder uses a conventional cast iron liner which means the engine can be overbored. The benefit is reduced costs in the event of a problem, plus the unit can be bored for adult pit bike use.

Valve design features a special “carbon cutter” valve stem which helps to prevent the build up of carbon on the stem, which could cause a valve to stick. This is an important feature when a unit will be operated at sustained low speed and low rpms. Valve adjustments are via rocker arms for ease of maintenance.

Automatic ratchet-type cam chain adjuster reduces maintenance, extends engine life and reduces mechanical noise.

Mikuni VM11 carburetor ensures crisp throttle response and great fuel economy. It also features an electric carb heater for reduced engine warm-up time and faster cold starting. This carb heater senses ambient air temperature and therefore will not function if it is 16 degrees Celsius or warmer.

Washable foam air filter reduces maintenance costs.

Smooth-shifting, 3-speed transmission with automatic centrifugal clutch eases the beginner into the basics of shifting, without the complications of a clutch. The auto clutch features means all the rider does is shift the foot pedal … there is no clutching involved.

Transmission ratios have been designed to compliment the engine’s power band.

CDI ignition system delivers a hot, reliable spark, sure starts and requires no maintenance.

Centrifugal oil filtering system is basically an automatic system that requires no maintenance.

Lightweight, upswept exhaust system features numerous heat shields to protect young riders for hot components. This exhaust system produces a quiet exhaust note which will keep the neighbors happy. A cleanable screen-type spark arrestor protects Mother Nature from stray sparks.

Chassis/Suspension:

Rugged “mini-size” steel back bone type steel frame provides rugged durability whether being ridden by a child or an adult. The engine mounts to the frame at three points, making entire chassis more rigid for superior handling.

Triangulated steel tube swingarm is both rugged and rigid.

Inverted 22mm Showa front fork offers a class leading 96mm (3.8″) of wheel travel providing confidence-inspiring control over rough terrain. The lower fork legs feature rugged plastic protectors that help to protect the fork legs from stone chips.

Monocross single shock rear suspension with 71mm (2.8″) of wheel travel delivers progressive suspension performance to smooth out rugged trails.

Low 555mm (21.9″) seat height provides a handling-enhancing lower centre of gravity and allows most riders to put both feet firmly on the ground for added confidence.

Long, motocross-style seat is low, comfortable and allows easy rider movement.

Front and rear 80mm drum brakes deliver strong dependable stopping power. The brake design and components are the same front and rear.

2.50×10 front and rear knobby tires feature a 4 ply design, and offer superb traction in the dirt.

135mm (5.3″) of ground clearance allows the TT-R50 to tackle modest obstacles.

Features:

All new rugged IS-inspired plastic body components resist damage in the event of a tip-over. There design gives the new TT-R50 that big IS look while also creating a narrow profile for easy rider movements. New components include: front fender, front number plate, side covers, rear fender and side air scoops.

Long flat IS style seat provides easy front to back rider movements.

Key operated, handlebar mounted ignition switches prevents joy rides when an adult supervisor is not around.

Rugged IS style handlebar features a re-enforcing cross bar for extra strength and a foam pad to protect the rider. YZ style grips give that big bike feel.

Special sealed battery design is low-maintenance and prevents leakage even during a tip-over.

Serrated steel folding footpegs provide excellent footing even in wet or muddy conditions.

Convenient handlebar mounted paddle-style choke lever is easily accessible.

On/off/reserve fuel petcock
