• The 49cc four-stroke engine feeds power through a three-speed semi-automatic transmission, great for learning and playing. It's got the style of a big YZ, but low enough for the little guys to climb aboard with a seat that's only 555mm (21.9") above the ground. Once they're going, you'll be glad to know, the TT-R50E is equipped with front and rear drum brakes to deliver strong, dependable stopping power. Like all Yamaha's, TT-R's are packed full of leading-edge engineering and stand up to our stringent standards for reliability. They're built to last. The only thing we can't do is stop your little ones from out growing them! But we've got their next Yamaha waiting when that happens.

Highlights
• 49cc, 4-stroke power
• Convenient Electric Starting
• Throttle Stop Screw
Key Features:
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 learning how to ride.
• Compact engine cases keep the engine narrow, making it easier for a smaller rider to get their feet firmly on the ground.
• Lightweight crankshaft design means crisp throttle response.
• 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.
• Revised 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 (heater doesn't function above 16 degrees C or warmer). Carburetor changes include "Electroless" nickel plating applied to valve seat and nickel silver needle valve. These changes are to counter act the negative effects of E10 (10% ethanol) fuels.
• Other fuel system changes include a revised fuel petcock, new fuel cap and new fuel cap rubber vent hose. These changes are again related to the use E10 (10% ethanol) fuels.
• 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 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
• Rugged "mini-size" steel back bone type frame provides rugged durability whether being ridden by a child or an adult. The engine mounts to the frame at three points, making the 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 rough trails.
• Low 556mm (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 movements.
• Front and rear 80mm drum brakes deliver strong dependable stopping power. The brake design and components are the same front and rear.
• 2.50x10 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-R50E to tackle modest obstacles.
Features
• Rugged YZ-inspired plastic body components resist damage in the event of a tip-over. This design gives the TT-R50E that big YZ look while also creating a narrow profile for easy rider movements.
• Key operated, handlebar mounted ignition switch prevents joy rides when an adult supervisor is not present.
• Rugged YZ 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
• Cosmetic improvements for 2011 include new silver coloured surface treatment for the gear shift pedal, rear brake pedal, footpegs, rear sprocket, and engine mounting bracket.
Safety Items
• Throttle stop screw allows parents or adult supervisor to control the top speed of the TT-R50E by restricting how far the throttle can be opened.
• Exhaust heat shields protect young riders from hot components
• Foam handlebar pad
• Keyed ignition allows parents to control use
• Upper and lower chain guards
IMPORTANT NOTE: Adult supervision and proper protective riding gear, including a helmet and eye protection are a must when a youngster is operating a TT-R50E.
