頭盔王與車友傾車經，最常被問及的「胎氣打幾多最慳油」。這個問題其實不能以簡單及一致的答案解答，因為每款車的設計、車手駕駛習性及行駛地點，均直接影響應打胎氣的多寡；即使是同一款車，只要駕駛環境及條件有變，車主也應該要有基本概念調整胎壓，確保電單車有效率地發揮最大性能。

Honda CRF450R作為賽道專用的場地車，車身設計均以「競賽」為主要考慮，不設頭燈、方向燈等安全性部件，不符合運輸處出牌的規格，無法在馬路行駛。不過由Honda歐洲分公司與西班牙Montesa在意大利的合資企業「Red Moto」特意將CRF450R改裝調整，全力保留此車的「純種」競速配置，同時加配道路安全部件及調整車款的排放標準，將此款場地越野車重新打造成可合法出牌在馬路行駛的版本CRF450RX Supermoto！

說起電單車界的「概念車」，有一定車齡的車友都會記得Honda在2008年推出的DN-01，除了車身設計夠劃時代般科幻前衛外（想像一下2008年普遍車款），是當年出街收視率最高的電單車，更搭載Honda廠獨家開發新型自動變速箱「HFT」（Human-Friendly Transmission）。承繼DN-01車系，廠方在2014年起斷斷續續推出同樣搭載自動變速系統的NM4系列，更因其科幻外觀，NM4曾與攻殼機動隊真人版電影合作。

近年各日本大廠投放不少資源在復古、巡航系電單車的設計開發。其中1985年已推出的Kawasaki Eliminator系列，外型看似美式巡航車，實際設計更適合在城市街道行駛，近年在亞洲地區掀起熱潮。Kawasaki今年特意推出日本版及歐洲版Eliminator，劍指Honda的同款電單車Rebel市場！

Car manufacturers generally recommend that car owners replace new batteries for motorcycles every year, but according to experience, the battery life of normal use can last for about 2 to 3 years. However, if you haven't been in the car for a long time, or forget to turn off the lights when you turn off the car and leave, the battery will be "dry pond". At this time, does it need to be recharged, or does the battery have to be replaced in full when it expires? Helmet King teaches you the easiest test method.

Imagine that every time you get in the driver's seat of a private car, the first thing to do is to adjust the seat position, the angle of the backrest, the rear mirror, and the angle of the steering wheel. The principle of motorcycles is actually the same, but Helmet King knows that many bikers have not done this. After buying a new car, they can simply fine-tune the rear mirror and drive with a key. In fact, as long as you simply adjust the handle, clutch/brake lever, and pedal position, you can improve comfort and provide better control. Why not?

If there is a warranty of 46, the car will be inspected at least once a year (the new car will be returned to the factory for inspection; the old car will be subject to compulsory annual inspection). Although there is no such mandatory requirement for motorcycles in Hong Kong, regular vehicle inspections are actually a good habit. Most of the small problems with motorcycle parts have to be disassembled and inspected before they can be discovered. If small problems are not dealt with in time, they will deteriorate into major problems in the long run, whether it is for driving safety or the owner's wallet.The gain is not worth the loss.

Brake oil and Lai (brake oil) are the two most important "oils" in motorcycle maintenance, and Brake oil is often overlooked. Most motorcycle manufacturers recommend that the brake oil be replaced every 2 years. How to judge whether the brake oil of your car expires and needs to be replaced? What impact will the deteriorated Brake oil have on the performance of your car? Let's discuss it together below.

A century-old heavy rainstorm caused heavy losses to many people, and many cars parked on the streets in the hardest-hit areas are believed to have died heroically. However, it is time to start again after the wind and rain. In case my car unfortunately becomes flooded in this black rain, should I go for maintenance? In theory, a flooded car can be repaired, but it may take a lot of manpower and material resources and a large number of replacement parts. In the end, the cost may be similar to buying a new car.

This summer is really hot and very hot, the somatosensory temperature is 45°C+ at every turn, and it is definitely hellish to stop the lights or even traffic jams in the city! Many bikers and friends around them may have tried their cars because the cooling water temperature is overheated and the fire is dead. If the location of the dead fire happens to be in the middle of the red tunnel or the highway, it is embarrassing and very dangerous! If you want to know how to understand that overheating the water temperature will cause a fire, you must first understand how the cooling system of a motorcycle works.
