• Overhead cam (OHC) design effectively reduces noise and vibration, makes burning more sufficiently, reduces fuel oil consumption and reduces discharge;
The Honda S90 or Honda Sport 90 or Super 90 was a 90 cc Honda motorcycle. It had a single cylinder OHC air-cooled engine linked to a four speed transmission.
Its both air and water cooled.
The 1984 is air cooled, 1985 and on are water cooled.
whay is it
air cooled.
The last YZ250 that was air cooled was 1981. 1982 is when they switched to water cooled engines.
Liquid cooled. The last "sport" bike to be air cooled was the WAY out of date Katana
Yes. Four cylinder air cooled engine.
race bikes are cooled by air air circulation but in sports bike they are cooled by oil coolant
This describes what happens in a convection cycle.
water cooled is better
Air cooled water cooled oil cooled Totally enclosed fan cooled Refrigerant cooled
