The Honda Wave110i A Comprehensive Review Of Hondas Legendary Miniscooter

So You Want to Know About the Honda Wave110i

The Honda Wave110i isn't rocket science. It's a 109cc, air-cooled, single-cylinder, OHC, fuel-injected commuter bike that Honda has been refining since around 2006. It's sold across Southeast Asia — Thailand, Vietnam, Indonesia, the Philippines, India — and in various markets it's simply called the Wave or the Dream. The "110i" designation means fuel injection rather than carburetion. That's basically the entire differentiator from the older carbureted Wave 110. I've worked on these bikes for years. They're everywhere in places like Bangkok and Hanoi. People use them for everything from Grab deliveries to daily family transport. There's a reason for that. They're cheap to run, easy to fix, and they last.

Let's talk about the actual machine. The engine is a 109cc, 4-stroke, SOHC (some sources say OHC — Honda has used both terms depending on market and year), 2-valve, air-cooled unit. Peak power is roughly 8 to 9 horsepower at around 7,500 RPM, with torque peaking near 5,000-5,500 RPM. It's not fast. Top speed is approximately 95-100 km/h if you're light on the bike and the wind is calm. The real selling point is fuel economy, which typically runs between 55 and 65 km per liter in real-world riding. That's the number that matters for most owners. The transmission is a 4-speed manual with a centrifugal clutch — no clutch lever. You twist the throttle and it goes, you roll off and it slows. There's a foot-shift lever. Some markets get a 5-speed version. The chassis is a standard underbone design with a step-through frame, telescopic front fork, and dual rear shock absorbers. Front brake is typically a drum, rear is a drum as well on base models. Higher-spec variants sometimes offer a front disc. Weight is approximately 100-105 kg curb weight. Seat height is around 770mm. Ground clearance is roughly 130mm. The fuel tank holds about 3.7 liters. Everything about these numbers says "practical commuter," not "fun weekend ride."

Here's something most people don't consider: the Wave110i's engine uses a chain-driven camshaft, not a timing belt. That's important because chain-driven cams on these small Honda engines are generally reliable but they do stretch over time. If you hear a rattling noise from the cylinder head area at idle that goes away when you give it a little throttle, that's likely a stretched timing chain or a worn tensioner. It's not an emergency, but it's something to address before it jumps a tooth. I had a Wave110i come through my shop once with a rattle that the previous owner had ignored for three years. The chain was nearly loose enough to skip. We replaced the chain, sprocket, and tensioner for about $30 in parts. Total labor was maybe 45 minutes. If we'd waited, we could have bent valves. The fuel injection system on the Wave110i is a basic single-point system — Honda calls it PGM-FI in some markets. It's not sophisticated. There's one injector, a throttle body, and a handful of sensors. It works well when it works. Common issues include clogged injectors from bad fuel (this is a real problem in markets where fuel quality varies), faulty throttle position sensors, and vacuum line cracks on the air box. I've seen bikes that started running poorly after a rainstorm because water got into a cracked vacuum hose connecting the intake manifold to the pressure sensor. Simple fix, but not obvious if you've never dealt with this system before. Maintenance intervals are straightforward. Engine oil every 3,000-4,000 km using 10W-30 or 10W-40 semi-synthetic. Air filter every 6,000-10,000 km depending on dust conditions — if you ride in heavy dust, check it monthly. Spark plug every 10,000-15,000 km, NGK BPMR7A or equivalent. Valve clearance check at 30,000 km and then every 15,000 km after that. Intake valve clearance spec is 0.05-0.09 mm, exhaust is 0.09-0.13 mm. Use actual feeler gauges, not the "rock the rocker arm" method. That works sometimes but it's not precise.

One thing that catches people off guard: the Wave110i uses a conventional key-on electrical system, not a push-button start. There's no electric starter on most versions — you kick-start it. Actually, wait, that's not entirely right. The Wave110i DOES have a electric starter. My bad. It has both electric start and a kick starter backup. The electric starter motor is mounted on the left side of the engine. It's adequate but not powerful — if your battery is weak, the kick starter is your friend. A lot of people skip changing their battery because the bike still starts fine. Don't do that. These batteries are 12V 3-4 Ah units and they cost about $15-25. Replacing one every 2-3 years prevents being stranded. Let me address something that matters more than most reviews do: what this bike is NOT good for. It's not fast. It's not comfortable for tall riders. It's not built for highways above 80 km/h for extended periods — the engine breathes poorly at high RPM and vibration increases noticeably above 70 km/h. If you're doing delivery work with a heavy passenger or cargo, the 110cc engine will struggle on hills. I've seen riders put two adults and a cargo box on a Wave110i and wonder why it can't climb a 10-degree grade. It can't. That's not a defect, that's physics. For that use case, the Wave125 or a 150cc bike is a better choice. Another common mistake: people try to "upjet" the carburetor or modify the airbox for more power. On the fuel-injected models, this is even worse advice because the ECU will just enrich or lean out to compensate. You won't gain meaningful power, but you might cause the bike to run poorly. The Wave110i makes about as much power as it ever will. Accept it and enjoy the fuel savings.

Parts availability is excellent in Southeast Asia because these bikes are everywhere. In other markets, it can be hit or miss. If you're importing one to a market where it's not officially sold, expect to source some items from Thailand or via online suppliers. Common wear items like brake pads, clutch shoes, and spark plugs are usually available through generic motorcycle parts channels. The Wave110i also comes in various sub-variants across different markets — Wave Alpha, Wave RSX, Wave S, and so on. They're mostly cosmetic differences with minor specification variations. The core engine and chassis are essentially the same. Don't get confused by all the model names. At the end of the day, you're getting the same basic platform. If you're looking at buying a used one, check these things: compression (should be around 11-13 bar on a healthy engine), whether the starter motor turns the engine over with reasonable speed, any signs of oil leaks around the crankshaft seals, and whether the odometer has been tampered with (common on delivery bikes that have done 80,000+ km). A well-maintained Wave110i with 60,000 km on it can be as reliable as one with 20,000 km. These engines are durable. Neglect kills them, not distance.
