Am I too small for this motorcycle? Duke – Sun May 14 17:38:31 2000 I’m only about 5’2″ and don’t have a problem, even though I can only touch the ground with the ends of my toes. Once you get a feel for the balance of the bike it’s not hard to keep everything upright. Only place I have trouble is pushing the bike backwards in a parking lot. Usually I just walk the bike (beside it) to where I can get on and get going. How does the EX500 compare to the EX250? Craig M. – Mon May 22 10:23:29 2000 I have both the EX250 and the EX500; both are Y2K models. The 250 is a screamer that performs well and can easily get me into trouble. My only complaints about the 250 are the excessive nose dive when getting on the front brake hard and the skittishness of the rear during high speed cornering. Both are easily corrected with suspension adjustments, I’ve just been too lazy to get the parts and do the work. A bit more wind protection would be great too. The 500 addresses these problems, the diving of the front end (to a degree); the rear’s skittishness and the wind protection. A plus for the 500 is the greater torque and power off the line; it pulls stronger (in my opinion) and will get you into illegal speed territory just a bit quicker than the 250. With greater weight, is has more stability in high speed and windy situations. Insurance is just about the same for both, with the 250 getting the nod for gas mileage. Service requirements are almost identical for both as well, being that they’re both parallel twins, the technology is the virtually the same. The downfalls of the 500: $2K more than the 250 (can do a lot to the 250 with that kind of money); buzzy mirrors, barely useful; heavier weight to have to push around the garage; lesser gas mileage (55-60 MPG; 250 pushes 70 MPG easily); engine is worse than a nervous dog shaking around at idle and at speed (here the 250 is far superior and much smoother). In my opinion, the 500 is a better suited for a larger rider, from a comfort standpoint. I feel I can stretch out a bit more on it than the 250 (I’m 5′ 9″, 160 lbs). The 250′s brakes are better tuned than the 500 and the shifter is much smoother. That may be due to the 3,500 mile difference between the two bikes. Bottom line, both bikes are great, the 250 is now my wife’s ride (mainly) and the 500′s mine (unless she steals the keys away). In time, I’ll make the adjustments to the 250; she doesn’t push it like I do.

Quick Guide to Maintenance Coolant liquid Coolant liquid -30ºC Crankcase oil (10w40) 500 cc. Electrode separation 0.6 mm. Forks suspension oil SAE 5 (Summer) SAE 2.5 (Winter) Fork suspension oil quantity200 cm3 Shock absorber spring length96 mm Front wheel pressure Standard 0.400 bar Competition 0.370 bar Rear wheel pressure Standard 0.350 bar Competition 0.300 bar -9- 1 Fuel – Petrol/oil mixture The motorcycle is fitted with a two-stroke internal combustion engine. This type of engine requires a mixture of petrol and oil. To ensure the correct working of the engine, the following are recommended: – Use high quality petrol, with an octane rating equal to or above 90 (RON + MON)/2 or 98 (RON). – Use 2T synthetic oil. Warning: – If the recommended oil is not available, use semi-synthetic oil. – Do not mix different oil-types. Mixture ratio: oil, 1.5% of petrol volume (50 parts petrol to every 0.75 part oil). Note: we recommend first preparing the mixture in a suitable container and then filling the fuel tank. Fuel tank This has a rapid access cap A and a vent hose B to allow gases produced in the tank to escape. – To open the cap, lift the clip in the direction shown by the arrow and turn to the left. Warning! Regularly check the cap seal and vent hose to ensure they are leak proof. Risk of spillage. -10- 3 2 Reserve Open Closed Fuel tap This has three positions: open, closed and reserve. The diagrams below show the position of tap A for each case. A Gear shift The motorcycle has a two- speed gearbox, which may be selected manually when the motorcycle is stationary, by moving the lever A in a horizontal direction, as shown by the arrow. Note: Select the gear according to the characteristics of the track
