Honda H100 / MB100

The Honda H100S is a two-stroke motorcycle introduced in June 1983, alongside the original Honda H100-A, which was released to the UK in February 1980. The H100-A was built for fulfilling the role of an economical, practical, lightweight commuter machine. It was designed for riders who preferred the simplicity of the two-stroke engine. In Honda style, equipment such as a fully enclosed chain, capacitor discharge electronic ignition (CDI), and a separate oil injection system allowed easy operation of the motorcycle with the minimum of maintenance and attention. The lowly-tuned engine gives adequate performance for use in normal traffic conditions, but does not consume high amounts of fuel. Under normal operating conditions, mileage to the gallon figures regularly exceed 80, often close to 100, impressive for a two-stroke and not far off Honda's own four-stroke commuting machines.The engine uses a reed-valve induction system, and the vibration inherent in single cylinder engines is largely cancelled out by the single shaft primary balancer.

The H100-S was introduced alongside the H100-A which continued in production until stocks were exhausted. The H100-S is a heavily revised version of the original, losing some of its more practical features as a result. This was felt necessary to give it a wider appeal. The oil tank was moved from being part of the fuel tank to behind the right hand side panel, the final drive chain casing was relieved for a sleeker, chrome plated top cover, the clocks were made separate from the headlight to allow for a new tachometer, and, strangely, the CDI ignition system was replaced by a contact breaker system (points).

March 1986 saw a largely cosmetic reworking of the H100-S, to form the H100-SII. This model received bolted-on frame down tubes which gave the appearance of a conventional cradle-frame motorcycle. The ignition system was reverted to CDI, and all other changes were in terms of paint and graphics.

Production of the H100-SII ended in 1992.

Many H100's were used as engine donors as a cheap performance upgrade for MB5's!

Honda MBX125

The Honda MBX 125F was produced between 1984 and 1985 and featured styling closely aligned to the VF and CBX models of the day. The spec was high featuring a liquid cooled single cylinder engine producing 12 bhp (for the UK learner law) with a top speed of 72 mph. It had Honda's latest Pro-Link rear suspension, comstar wheels with a then fashionable 16" front with a bikini fairing and belly pan, it certainly looked trick compared to its contemporary's of the day. Unfortunately the Honda couldn't quite cut it performance wise in restricted form against the RD125's (that were easy to de-restrict) and only lasted 2 years before being replaced with the Italian made NS125F that learnt heavily on Honda's racing success. For other markets the bike boasted a 22 bhp engine with ATAC power valve.

Honda said, "Feast your eyes on the MBX125F, a world leader for sparkling sports-styling and proven road safety. From its aerodynamic handlebar mounted bikini fairing to its racing contoured seat, from the lightweight ComStar wheels with dual piston caliper front disc to its flexible 2-stroke liquid cooled engine with balancer and 6-speed transmission, everything tells you that this is the peak of MBX achievement."

Honda MM50 Raccoon

The MM50 Raccoon was released on March 1, 1980,  designated as model AD02 and was only sold in Japan. Based on Honda's first 50cc 2-stroke sports bike MB50 released in 1979, it was developed with the concept of "leisure bike running lightly in downtown area". The MM 50 was styled as a custom cruiser and the terms  "easy ride" and " Harajuku bike " were also used in advertisement publicity .

The MM50 shared a lot of parts with the MT 50 and dual purpose off road style model. The air-cooled 2-stroke with reed valve with built-in AD02E type 1-axis balance shaft. The single cylinder engine was tuned to make the performance more suitable as a city commuter as opposed to AC01 E type engine for MB50. Revised tuning gave stronger low to medium torque.

Maximum power: 7 ps / 9,000 rpm → 6 ps / 7,000 rpm
Maximum torque: 0.56 kg - m / 8,000 rpm -> 0.62 kg - m / 6, 500 rpm

Featuring a front 17"and a rear 14" spoke wheels, a carry rack, a low exhaust and a low seat with a ground height of 700mm . It also featured more forward mounted foot pegs (compared to the MB5) with a linkage for the gear lever. On the design side it features a rectangular headlight and an X shaped backbone frame.

It was discontinued due to a model change to MBX 50 · MTX 50 R due to the introduction of the water cooling engine of MB 50 · MT 50 of parts sharing vehicle in 1982 .

The following bike is owned by Honda M Club member Chris Bronstijn who bought this unused bike in the Netherlands, before this the bike was in a museum in Switzerland!

Members bike: Dan J's MBX80 in Practical Sportsbike Magazine

Dan J's bike from www.mbx80.co.uk has just been featured in the latest Practical Sportsbike Magazine in the 'in your shed' feature, magazine out today!

M Club - first event?

Currently I am pursuing the idea of having a Honda M Club (uk) stand at the Classic Motorcycle Mechanics show at Stafford in October. I have spoken to the organisers and we are now on the club list, at this point in time I don't know if we will be aloud to exhibit at the show as I here they have a waiting list, I am just exploring options.

So.... My question is IF we were able to exhibit would anybody be interested in joining in, exhibiting their bike and sharing costs? If this is something you are interested just comment on this thread with the model of bike you would like to display. At this point its still hypothetical so I'm not going to hold you on it if you change your mind at a later date!!

cheers
