PRINCIPAL ELEMENTS OF THE MOTORCYCLE KEYS With this model, you will be given a set of keys, which are used for the Ignition switch/Steering lock. These keys are joined together by a small plastic panel, where the key number is engraved. We recom- mend that this number is kept in a safe place in case the keys are lost.

CLUTCH LEVER The clutch lever is situated on the left-hand side of the handlebar. To activate it, pull the lever towards the grip or handlebar. FRONT BRAKE LEVER The front brake lever is situated on the right-hand side of the handlebar. To activate the front brake, pull the lever towards the handlebar.
Any acid spilt could cause damage to clothing or bike bodywork. Rieju cannot be held responsible for any damaged caused by incorrect battery handling. The SMX is fitted with a battery, this is located under the seat. To get to battery the seat has to be removed, a 10mm bolt under the mudguard secures the seat to the bike.
If the motorcycle has no oil left, the motor would seize up immediately with serious tech- nical and costly consequences for the user. RIEJU recommends using Injection System oil. PETROL TANK To get to the tank, open it using the stopper of the tank, turning it anti-clockwise.
PETROL TAP The petrol tap is situated on the right-hand side of the vehicle, under the fuel tank. It has three positions: OFF: with the lever in this position, the fuel will not go through. Put the lever in this position when the motor is not running when parked and garaged.
CHECKS BEFORE USING MOTORCYCLE. Check the following points before using your motorcycle: Items to be checked Check-up 2 Stroke Oil tank Check the level and fill up if necessary Lights and indicators Check if they work correctly Speedometer cable Check if it works smoothly and lubricate it Front and rear brakes Check the brake pads for wear and test brakes Accelerator grip...
ROUTINE TESTING BRAKE FLUID LEVEL AND BRAKE PAD WEAR Check that the level of brake fluid is correct, if not, Check for brake pad wear. If the pad material is less than 2mm thick, the pads should be replaced. If the pads are not worn out, top up the brake reservoir with brake fluid.
Dot 4 brake fluid. If the reservoir is empty please go to your local Rieju dealer. Always remember that the above must be carried out by a RIEJU official service.
THROTTLE TWIST GRIP Ensure it works correctly, by turning the grip and verifying if the free play is correct. The grip should return to closed position when released. LIGHTS, INDICATORS AND WARNING LAMPS Check operation of all lights, and direction indicators plus the oil warning lamp and petrol reserve panel lights.
Turn the ignition key one position clockwise and check the engine is in neutral, with the throttle closed depress the kick start to turn the engine over in MRX model. After a few kicks the engine should fire, allow the kick start to return to its rest position.
TO RIDE AWAY Pull in the clutch lever and put the motorcycle in first gear (Down one click), slowly release the clutch lever while at the same time accelerating slowly once moving allow the clutch lever to go its rest position (OUT) and ride away.
CARBURETTOR The carburettor provides the correct petrol air mixture to the engine. It the settings are tampered with poor performance and/or overheating may occur. If you have any problems please refer to your Rieju dealer.
PRS (Progressive Racing System). The MRX PRO/SMX PRO model is prepared with a Gas hydraulic mono shock absorber with a separate reservoir. Manual adjustment to the suspension pre-load is achieved using the threaded brass rings at the base of the unit.
COOLING SYSTEM The radiator is mounted on the front right-hand side of the motorcycle behind a protective grill; The radiators propose is to maintain a constant engine temperature by cooling the hot water which is pumped around the engine. To check the level of coolant, carefully undo the radiator cap off and top up if necessary.
SPARK PLUG CHECK The spark plug is an important part of the motor and it is easy to check. Take the spark plug out and check it periodically, the high combustion temperatures and carbon deposits may effect the efficiency of the engine.
AIR FILTER To ensure that the engine runs correctly, the air filter must be kept clean and oiled. To get to the air filter remove the rear right side panel, by undoing the two allen screws, Remove the black cover of the air box, which is held on by three screws, (See picture) and extract the filter.
Page 28
After removal, check to see if the foam filter is blocked, in which case wash in paraffin, apply some air filter foam oil then squeeze the filter material between your hands to remove surplus oil. Do not wring out the filter element, as this will damage the foam. When refitting the air filter sure that the foam fits the box correctly so that no air can enter the engine without being filtered.
TRANSMISSION CHAIN ADJUSTING AND LUBRICATION The MRX / SMX is fitted with a chain tensioner to help maintain the correct chain tension, nevertheless the chain needs to be inspected and lubricated at regular intervals. If the bike is operated in the deres- tricted mode the wear on the chain will be greater due to the extra power being transmitted to the rear wheel.
Page 30
Try not to over tighten the chain, as it will stretch and wear the sprockets much quicker and may dama- ge the gearbox. When the correct adjustment has been achieved check the wheel alignment. To do this, the slits of the adjustment plates should be in the same position on both sides of the swing arm.
Drainage bolt GEARBOX OIL CHANGE. The gearbox and the clutch are lubricated by the action of the same gearbox oil. The recommen- ded oil is SAE 10W/40, with a total gearbox capacity of 820c.c. A drainage bolt situated in the bottom right-hand side of the motor empties the gearbox.
3. Using a hose pipe remove the degreasing agent and dirt, but only with the pressure that is necessary. (DO NOT USE A PRESSURE WASHER.) NOTE: Rieju is not responsible for the use of degreasing agents that may stain or mark the body work or chassis.

4. Once the dirt has been removed, wash all the surfaces with warm water and soft detergent. To get to the difficult areas, use a bottle-washing brush or something similar. 5. Immediately rinse with cold water and dry all the surfaces. 6.
