The finals of Ultra Light weigt Class.

Hairpin curve

Combat with CR110 and CR110. But #300(right) engine is 55cc. Owner expanded the bore of barrel. Essentially, should have done different class. Of course, #255(left) engine is original 50cc. Mr.Naitoh accorded to sportsmanship.

Second group. Bridgestone EGRA, Honda CS65, and two Honda CR110.

Third group.

Bridgestone GB1 ridden by Asao Kanai. It was very fast bike, even though It completed just before the race.

#255 shake off his competitors and make it to the line first after all.

A record holder is Keiji Naito between this several years. A motorcycle keeps evolving little by little, and the skill of rider improves, too. Many riders and motorcycles challenged him. But, he always defeat them. Then, the best lap reached "1'26.639" at last. For several years ago, the course record of this class was level of one minute and thirty second. Though it is some CR110 that account the high rank of this class, I expect Suzuki TR50 and Bridgestone GB1 challenges.
