Motorbikes are a vehicle that is probably too familiar to us, but not everyone knows what kind of engine their car is using, so let's take a look at Mechanical Funny to learn a bit about motorbike today.

Currently there are about 9 types of internal combustion engine used for motorbikes, which are classified according to cylinder arrangement criteria on engines.

𝟭.) 𝐒𝐈𝐍𝐆𝐋𝐄 - 𝐂𝐘𝐋𝐈𝐍𝐃𝐄𝐑

- Single cylinder engine is the first engine of the internal combustion engine. This type of engine appears on: motorcycles, scooters, 3-wheelers, dirt bikes, self-driving cars, scooters, especially on Honda CBR250R. Single-cylinder engines are also used on agricultural implements, garden machines and tractors

- Whether it is a 2-stroke or 4-stroke engine, the single cylinder engine is also composed of 1 single cylinder and 1 single combustion chamber, responsible for carburetor and fuel combustion, generating power for the engine. work.

𝑨𝑫𝑽𝑨𝑵𝑻𝑨𝑮𝑬𝑺:

- Structure simple and compact.
- Low cost
- High torque at low rpm
- Easy to apply air cooling system.
- The most cost-saving among the 9 types of motorcycle engines, which helps to reduce vehicle weight and make the operation more efficient.

𝘿𝙄𝙎𝘼𝘿𝙑𝘼𝙉𝙏𝘼𝙂𝙀𝙎:

- When working, the engine vibration is difficult to eliminate so it is often found on off-road vehicles and small-displacement ordinary cars.
- Requires greater flywheel and greater ability to maintain continuous energy.
- Changing the speed will be difficult and the car often shakes because there is only one resource, so it does not create a balance during operation.

CAR LINES USING Single Cylinder engines:

- Dirt-bike, scooter models

- Especially on Honda CBR150R CBR250R, Fz16, Fz150, KTM Duke etc.

𝟮.) 𝐏𝐀𝐑𝐀𝐋𝐋𝐄𝐋-𝐓𝐖𝐈𝐍

2-cylinder in-line engines are also known as parallel 2-cylinder engines

𝑨𝑫𝑽𝑨𝑵𝑻𝑨𝑮𝑬𝑺:

- Simple, compact and sufficient moderate capacity, suitable for everyday travel.

𝘿𝙄𝙎𝘼𝘿𝙑𝘼𝙉𝙏𝘼𝙂𝙀𝙎:

- Vibration makes it difficult to suppress accuracy. Often used for cars of everyday use, traveling with long distances.

Commonly found on classic models of Honda NC750X, Triumph Bonneville Thruxton, Kawasaki Versys 650, Kawasaki Ninja 300, Yamaha R25, Yamaha R3.

𝟯.) 𝙑-𝙏𝙒𝙄𝙉

- This engine has a V-shape so it is called V-Twin.

- V-Twin engine features outstanding torque and power balance, suitable for low-focus cars and is the best choice for cruiser believers.
- According to MotoSaigon, the V-Twin engine on many Ducati like Monster 796, because the position of the front cylinder almost parallel to the ground forms an L-shape, so the term L-Twin.

𝑨𝑫𝑽𝑨𝑵𝑻𝑨𝑮𝑬𝑺:

- Balance between power and torque, suitable for vehicles with low center of gravity.

- Can create vibrations (especially in the narrower V-Twin engine configuration)

- Difficult to cool the cylinder behind

- Generates less power per displacement unit than a 3 or 4 cylinder engine

Often used for Cruisers. The Ducatti, Harley-Davidson and Moto Guzzi, Honda Shadow, KTM 1290 Superduke R. "De pa" models are faster than 4-series models, such as the Ducati Monster 796 pa stronger than the Cb1000, Z1000.

𝟰.) 𝐅𝐋𝐀𝐓-𝐓𝐖𝐈𝐍 (𝐁𝐎𝐗𝐄𝐑)

Boxer engines (flat engines) are typical symbols of the models from BMW, Ural, Dnepr, etc. of the Soviet Union. The engine with the cylinders is placed horizontally (or flat) and the pistons lie symmetrically with the crankshaft.

𝑨𝑫𝑽𝑨𝑵𝑻𝑨𝑮𝑬𝑺:

- Can be easily placed in line with the gearbox and drive shaft
- Creating less vibration, a longer life span
- Reach a stable balance.
- Low center of gravity, large torque.
- Good cooling system

𝘿𝙄𝙎𝘼𝘿𝙑𝘼𝙉𝙏𝘼𝙂𝙀𝙎:

- Large motor width. Bulky size. It requires a different and complex chassis fabrication process

- The tilt angle is limited

- Production costs will also increase due to the need for 2 cylinder heads

USED CAR LINES:

- German luxury sports car manufacturer - Porsche and Japanese automaker - Subaru.

- Featured on BMW Adventure, BMW sidecar, Ural sidecar, Dnepr, BMW R 1200R .

𝟱.) 𝐈𝐍𝐋𝐈𝐍𝐄 - 𝐓𝐑𝐈𝐏𝐋𝐄

This type of engine has the advantage of being well balanced with the crankshaft forming a 120 degree angle, overcoming the disadvantages of 2-cylinder and 4-cylinder engines.

𝑨𝑫𝑽𝑨𝑵𝑻𝑨𝑮𝑬𝑺:

- Good dynamic balance with 120-degree angular distribution axis for each cylinder. Overcoming disadvantages between V-twin engine and 4-cylinder

- Small engine, light vehicle weight, larger interior compartment, smooth and smooth running car suitable for urban, plain and narrow roads,

- Less fuel consumption, lower car purchase cost.

𝘿𝙄𝙎𝘼𝘿𝙑𝘼𝙉𝙏𝘼𝙂𝙀𝙎:

- Vehicles operating will be weaker, poor acceleration and no ramming because the vehicle is designed with small weight.

CAR LINES:

- Often used on Triumph Triple 675R, Benelli, Yamaha FZ9, Mv Agusta Brutale 800 etc.

𝟲.) 𝐈𝐍𝐋𝐈𝐍𝐄 – 𝐅𝐎𝐔𝐑𝐒

Inline-four-cylinder engines (I4 - Inline-four) are the type of engines often found on Japanese sports cars.

𝑨𝑫𝑽𝑨𝑵𝑻𝑨𝑮𝑬𝑺:

- Engine smooth and powerful operation, howling sound

𝘿𝙄𝙎𝘼𝘿𝙑𝘼𝙉𝙏𝘼𝙂𝙀𝙎:

- Larger size than the same-sized V-Four engine. Often used for sports cars with a capacity of 600 cc or more

CAR LINES:

- 4-cylinder engine in line often found on Japanese sports cars such as Honda CB750, Z1000, Cb1000, Yamaha R1, R6, Honda CBR1000 RR, CBR600 RR and so on.

𝟳.) 𝙑-𝙁𝙊𝙐𝙍𝙎

𝑨𝑫𝑽𝑨𝑵𝑻𝑨𝑮𝑬𝑺:

- Strong, smooth and durable operation.

- High performance

𝘿𝙄𝙎𝘼𝘿𝙑𝘼𝙉𝙏𝘼𝙂𝙀𝙎:

- High production costs.

- Heavier and more complex than a 4-cylinder engine

CAR LINES:

- Usually applies to sport touring road models.

- A typical engine on Yamaha V-max, Honda VFR, Aprilia RSV4, Honda RC213V, Ducati Desmosedici models.

𝟴.) 𝐅𝐋𝐀𝐓 - 𝐒𝐈𝐗

- Six cylinders are placed consecutively. Horizontal 6-cylinder engines are quite rare, but are still used on

𝑨𝑫𝑽𝑨𝑵𝑻𝑨𝑮𝑬𝑺:

- Durable and smooth.

𝘿𝙄𝙎𝘼𝘿𝙑𝘼𝙉𝙏𝘼𝙂𝙀𝙎:

- Heavy, complicated structure when manufacturing and repairing. Therefore, often equipped on high-end touring models.

CAR LINES:

- Models with large displacement motorcycles, especially Cruiser models.

- Honda Gold Wing

𝟵.) 𝐈𝐍𝐋𝐈𝐍𝐄 - 𝐒𝐈𝐗

𝑨𝑫𝑽𝑨𝑵𝑻𝑨𝑮𝑬𝑺:

- Unique, smooth operation, reach high speed.

𝘿𝙄𝙎𝘼𝘿𝙑𝘼𝙉𝙏𝘼𝙂𝙀𝙎:

- Complicated and large in size.

Basic Tyre Knowledge

The sidewall provides valuable information about the tyre including the specifications, the brand, and the type of construction. All numbers are standardized and recognized by tyre manufacturers around the world.

Codes:
1. Section Width(mm)
2. Aspect Ratio(Section height as a percentage of the section width).
3. Rim Diameter(in)
4. Load Index
5. Speed Rating
Load Index and Speed Rating
Load index corresponds to the load capacity while speed rating is designated using letters from J to Z and represents the maximum speed of the tyre. These two factors are interdependent. Please refer to the tables below for the load index and speed rating.
