Honda Super Dio AF-27/28 scooter review

The second generation scooters - Honda Super Dio (AF-27) - began to be produced in 1990.
They differed little from the previous model Dio AF-18 - except in design. Even the AF18E engine remained almost unchanged. Three main variants of the Super Dio were produced: the basic AF-27 model with drum brakes and an AF18E engine, the AF-28 SR model with a front disc brake and an uprated AF18E engine, and the AF-28 ZX model - all the same, plus instead of a trunk she had a spoiler with a brake light.

Honda scooters of the Super Dio series continued to be produced until 1999. At a certain period, this design was produced under the name Dio Fit, with a new design of plastic body kit and headlights.

Advantages and disadvantages

The Honda Super Dio scooter is one of the most popular and beloved models among scooterists. The secret of success is a simple and reliable design, which has already been well tested on the previous Dio AF-18 model. The successful design is still considered quite modern to this day.

As mentioned, the design of the AF-27 is not much different from the AF-18. The slightly updated AF18E engine is almost completely identical to the previous one - the only difference is the crankshaft diameter. The brake system also remains unchanged.

The engine easily develops 60-65 km/h, although if the components are in good condition, the scooter can be accelerated to 70 km/h. The AF-28 switch has a speed limiter, so you can only reach 70 km/h after replacing the switch.

Despite the fact that the AF-27/28 is designed to carry one person, the engine power is enough for two. The unpretentious engine runs on any gasoline, even 80 is suitable for it, although, of course, it is better to fill it with 95. Fuel consumption under ideal conditions is about 2.5 l/100 km.

The Super Dio scooter can carry more things than its predecessor. The underseat storage area has been enlarged by relocating the battery, and a front pocket has also been added. On the AF-28 ZX model, the rear trunk is replaced by a spoiler with an LED brake light.

Honda scooters are unpretentious to road conditions and are well protected from dust and water getting into the engine. The muffler does not suffer damage from curbs or speed bumps - either the bottom or the running board takes the blow.

The suspension also remains structurally the same, which means that the AF-27/28 will feel great in the city. The scooter maneuvers wonderfully in traffic jams, and its element is smooth asphalt. Of course, if necessary, you can ride on dirt roads, although this is no longer very comfortable.

The AF-28's front disc brake is especially effective on asphalt surfaces.

Spare parts for Super Dio are still produced today, so if necessary, it is easy to buy any part. As always, these scooters are very repairable. The vertical arrangement of the cylinder in the engine allows access to the piston group without removing the engine.

AF-27 Model Review

We can say that the Honda Dio 27 is a restyling of the af-18 model, because the appearance and technical components have remained virtually unchanged.
But still, some changes have occurred; the scooter is now equipped with a full-size compartment for a helmet in the central trunk; in addition to the helmet, it is convenient to store many small items there.

In addition, it uses a new dual-focus head optic for the slim type, integrated with a tilt-angle lens (Kirpton 35/30W gas actuation valve), and a large rear combination lamp integrated into the body.

Engineers have developed measures such as the layout of the fuel tank under the floor, as well as the large capacity (4 → 5 l) petrol tank, providing ample space in the trunk, it is convenient and functional.

In addition, an internal stand is equipped on the inside of the front panel as standard, making it easy to use in everyday life, providing a seat height (700mm) with good legs and generous space.

Production Features

The Honda Dio 27 scooter was in such demand that at first there were problems with exports, since the Japanese market also needed an economical, practical and convenient two-wheeled vehicle. After part of the production facilities were built in Taiwan, the production of cars increased significantly, and they ceased to be in short supply.

The designers experimented with the type of braking system, after which they chose a more modern disc unit. Several limited edition mopeds were produced, which were distinguished by a completely different dashboard design and bright, unusual body colors.

Repair instructions for Honda Dio

Tips for repairing Honda Dio are available to any motorcycle enthusiast. In particular, we will talk about servicing the vital parts of an iron car: engine, carburetor and transmission.

The carburetor is a sensitive and important part of the scooter. The slightest breakdown will stop the operation of the entire machine. Owners are often afraid to touch carburetors because they are not confident that they can assemble them correctly. However, everything is not as scary as it seems at first glance. Honda Dio is recognized by experts as the most convenient and suitable representative for disassembling and cleaning the carburetor. The fact that it is not covered with plastic, its location above the transmission and the ease of setting up the mechanism speak in its favor.

• the adjustment process is carried out on a well-warmed engine;
• if there is any doubt about a blockage, clean the carburetor and rinse thoroughly;

The setting itself involves adjustment:

1. idle move;
2. quality of the mixture (by moving the needle and using;
3. specialized screw;
4. amount of fuel in the float chamber;

Honda Dio engine repair

The engine is the heart of the scooter. Principles for eliminating basic breakdowns:

1. piston wear and increasing fuel and lubricant consumption are caused by low compression (below 8.0 kg/cm3 with a norm of 9.5-10.5); it is necessary to bore or change the cylinder-piston group;
2. a clear and loud knocking sound at the bottom of the cylinder, often when throttling, indicates wear of the piston skirt—replace the piston or the entire c/p group;
3. the engine stalls, losing power, usually when it is clogged - cleaning is required: burn it, or cut it, clean off the carbon deposits and weld again; the exhaust window can be cleaned;
4. does not start, does not work well, does not hold idle speed if the seals are broken (fuel leaks form there) of the cylinder, crankcase, head gasket, crankshaft seals are worn out - replace the seals and gaskets;

The transmission also becomes unusable, and, sooner or later, it is replaced. The process of replacing the variator is not particularly difficult. The main thing is to choose the right belt - this will allow you to keep its settings unchanged. For example, a very long belt will begin to slip, and a wide one will reduce the range of gear ratios and will not reach the maximum width of the cones.

Interesting Facts

The developers didn't stop there. Next, a model with an electric motor was released, which was equipped with alkaline batteries. They are located in the compartment where the fuel tank was previously located. The battery is charged from a standard network. The scooter was produced for domestic consumption and was not exported.

Since the mid-nineties of the last century, the Honda Dio 27 moped has been equipped with a special anti-theft system. It is a special canopy that hides the ignition switch. This solution made it possible to reduce the percentage of thefts, since opening the protection without special tools is quite problematic. To unlock the curtain, you need to enter a digital code known to the owner. However, there were also incidents: if the code was forgotten, it was necessary to contact a special service and turn off the entire system.
