It was held on July 16 and September 24, 2018, the 20th anniversary event of the opening of the Honda Collection Hall on the south course of Twin Ring Motegi. Although it was a racer and like in the usual dynamic confirmation test. This time as a commemoration of the 20th anniversary, a special motorcycle running was executed. Epoch-making motorcycle from the dawn of the Honda to the present showed off running. This paper introduces NSR50 which will be called N Tribe later.
3/4 Scale Model of WGP Racer "NSR500"
In the world of the scooter race which peaked in 1986, 10-inches or 12-inches mini bikes with a wheel diameter of 10-inches and 12-inches emerged in the feeling of play, such as SUZUKI GAG and YAMAHA YSR50. It began to see signs that mini bike races became popular on behalf of scooter racing. In order to introduce a base machine that allows more full-scale racing, Honda embodied the full-scale specs that overwhelm others on a 3/4 scale with "NSR500" participating in WGP as a motif.
[HONDA NSR50 1987] A compact body size, but it is a sports bike that you can enjoy the pleasure of maneuvering by full rigid equipment such as high rigid frame, front / rear disc brake, full fairing etc. It was incorporated a uniaxial balancer to reduce vibration. ■ Water-cooled 2-stroke Single Cylinder Piston Lead Valve 49cc 7.2ps / 10000rpm 85kg 6-Return Gear
[Reprint Impression] YSR is no longer an enemy
"Wow, this is good! It was a ride test ride, but YSR does not become a competitor. First of all, the front and rear disc brakes match very well with a full suspension and a rigid frame . In the case of this type of motorcycle, It get some risk to make this size such as tuck in. There is absolutely nothing for this one!! Since it was with a limiter this time, it has reached the limit of the engine in the middle of the straight but still the lap time was 42 seconds 70. If removing the limiter, I will overtake YSR 80.
If I want a greed, I would like a cross ratio for the second to fourth gear for the race. Then you can enjoy cornering pretty much, even with the limiter. because it is three-quarters scale of NSR500, it is better not to over-action. Because the quick operation responds sensitively, riding smoother can ride faster. It is fun to do the same ride as my F1. I love this. Because it is a water-cooled engine, it is also strong against heat sag. I will participate in Suzuka 8 hours endurance with this. *From Young machine August 1987 issue
Impression Rider was Masayoshi Oshima, the circuit course was Tsukuba Circuit East Course.

The NSR50, which brought up the world champion
Through encounter with the "Aoki Brothers", NSR 50 will make a big change in the world of mini-bike racing which was showing a prosperity in various places. At Gunma Haruna circuit, Takuma, the second son, achieved Winner's accomplishment for three years in a junior open class. The third son Naochika also won the kids class and won the name of "Gumma's Aoki three brothers". Takeshi Tsujimura, Tomomi Mako, Yuichi Takeda, Daijiro Kato also played an active part in NSR50 on other circuits. "World champion was on NSR50" "Great rider grew up with NSR50" is no exaggeration.
In around May 1987, Honda tested a prototype model that tuned the suction / exhaust system for marginal performance at the Haruna circuit, the eldest son of the three brothers Aoki, Nobuatsu Aoki (15 years old) .A face picture telling the line "This is very fast !! Dad, buy this" is on the upper right.
