One of the rare three-wheeled scooters on the market, the Tricity is a beginner-friendly option for city riders. It’s easy to use and offers a compact-but-comfortable seating design.

Moreover, the presence of a second wheel at the front increases the Tricity’s road grip and stability.

If you’re looking for an affordable and efficient three-wheeler, the Tricity is a suitable option.

However, it is important that you are familiar with the common problems associated with this scooter, so you know what to prepare for.

To assist you, we scoured online forums to gather complaints from real-life owners of the Tricity 155 scooters.

Based on our research, here are the most widespread issues affecting the Yamaha Tricity 155 models:

1. Widespread Engine Stalling Problem

No rider wants (or expects) his scooter to stall during a ride. Not only does stalling lead to time wasted on the roadside, but it could also put you at risk.

Some Yamaha Tricity 155 models stall during a ride. In one case, diagnoses traced the problem to a loose primary fixed sheave nut. According to the recall information given, the nut may loosen while riding because of improper tightening torque.

Should this happen, the primary sheave may be exposed to the crankcase cover, causing engine noise and stalling.

Luckily for owners, Yamaha recognized the problem and issued a recall for the affected scooters.

It further instructed to inspect and repair the scooters (by increasing the tightening torque in the primary sheave nut).

If your Tricity scooter stalls for no reason, measure the tightening torque on the primary sheave nut. If it’s not up to spec, use a torque wrench to tighten it. However, if your inspection doesn’t reveal any problem with the nut, then it’s advisable to have a mechanic check your scooter.

2. Scooter Doesn’t Start

Some owners have complained about starting problems on the Tricity 155 models. A particular user reported that his scooter failed to come to life even after he twisted the key in the ignition.

While the rear light came on, the indicators, headlights, brake lights, etc., refused to come on. Moreover, the starter didn’t work and the engine never showed signs of turning over.

This meant the scooter couldn’t run despite his efforts at starting it.

If you’re in the same situation as the rider above, the best thing is to conduct a thorough examination for the scooter. Possible causes include:

I. Battery issues:
A dead battery can cause a scooter not to start. Batteries can die even if they aren’t used. For example, if you leave your scooter parked for two, three weeks, the battery will lose its power.

In addition, batteries suffer parasitic drain. This refers to a situation where faulty bike computers or poor grounded wires cause a battery to discharge.

If this continues, the battery will eventually run out of power, which means the scooter can’t start.

II. Blown fuses:
This is an oft-reported cause of starting problems on the Tricity scooters. If your scooter has a blown fuse, it will sound normal when you try to start it but won’t come to life. This is because the fuse cannot produce the required spark for the spark plug to ignite.

To check for a blown fuse, look for black residue on the main fuse or disconnected fuse wires.

III. Bad spark plugs:
If your scooter merely turns over but doesn’t start, chances are you have bad spark plugs.

IV. Bad starter:
As with components, electric starters wear with time. If the electric starter is worn, you may get a clicking/buzzing sound when you engage the starter, but the scooter won’t run.

Possible solutions: After your inspection, endeavor to replace the faulty component.

But if these components are in good condition, then it may be time to consult a technician.

3. Riders Experience Excessive Vibration

Some Tricity riders complained about the tendency of the scooter’s handlebars to vibrate during rides. Per reports, the stiff suspension and increased air pressure in the tires may be responsible for handlebars vibrating excessively.

Although Yamaha placed rubber isolators between the forks and the bars, the problem persisted.

A quick fix for this problem is to reduce the air pressure in the tires. This will help decrease the wobbling and eliminate the handlebar vibration.

Also, the Tricity is known to vibrate excessively while idling, e.g., at a red light. You can stop the vibration by revving the engine, although this may lead to higher fuel consumption and transmission wear.

Besides, the Tricity is best used on smooth roads-riding this three-wheeler on uneven roads can be uncomfortable.

4. Storage Capacity Is Poor

While the Yamaha Tricity is a good scooter, its inadequate cargo capacity is a sore point for owners.

Compared to other scooters, the Tricity has limited storage options.

For example, there are no mini-compartments for small objects such as wallets or phones. The under-seat storage can only fit one full-face helmet, which may disappoint if you have more than just a helmet to store.

For a scooter its size, the Tricity’s lack of storage space is disappointing. There is a solution, though-you can purchase the optional luggage rack/case for increased cargo-holding capacity.

Be prepared to shell out some serious cash for this component, though.

5. Performance Is Underwhelming

Given its scooter status, we weren’t expecting the Tricity to be a speed demon. Still, we can’t help but notice the underwhelming amount of power available with this scooter.

The previous model used a 125cc motor that produced 10.9 horsepower and 7.7 lb-ft of torque.

The newer model features a bigger 155cc engine but is still underpowered at 14.8 horsepower and 10.6 lb-ft of torque. With these numbers, it’s obvious that the Tricity isn’t the fastest scooter out there.

If you want a speedy scooter, you’d want to look elsewhere.

6. Seating Is a Bit Uncomfortable

Some riders have complained that the seat on the Tricity model is too cramped, especially for taller riders.

While the discomfort isn’t particularly pronounced, long trips may leave you feeling sore. There is a “comfort seat” available (it comes with a backrest), but it will set you back a tidy $400.

General Pros and Cons of the Yamaha Tricity 155

Here are some benefits and drawbacks of the Yamaha Tricity 155:

Pros of Yamaha Tricity

The following are some qualities of the Yamaha Tricity 155:

1. Unique Three-Wheel Chassis: The Tricity uses a light but sturdy three-wheel chassis design. This allows for increased control and stability regardless of road conditions.

In addition, the low weight of the Tricity’s chassis helps increase its maneuverability. This makes it suitable for novice and expert riders.

2. Good Brake Performance:
The Tricity comes with dual 220mm diameter front brake discs and a 230mm rear brake disc for increased stopping power.

It also comes with Anti-Lock Brake System (ABS), which prevents wheel lockup under hard braking.

Even better, it features Yamaha’s Unified Brake System (UBS), which helps improve brake performance.

This feature optimizes the front and rear braking power when you pull the left lever and when you operate both levers simultaneously.

This ensures you get smooth and efficient braking.

3. Good Ride Quality:
Unlike the Tricity 125, the Tricity 155 offers plenty of ride comfort for riders. It features a bigger and wider footboard that reduces pain in the legs during trips. The motorcycle also has a longer and flatter dual seat that gives riders a comfortable riding position. Besides, the seat is designed such that riders can get on and off the scooter quickly.

4. Innovative Leaning Multi-Wheel System:
Exclusive to Yamaha, the LMW system offers riders confident handling and control.

This is particularly useful when attempting to twist at corners as it gives you more confidence during those turns.

The LMW system features a parallelogram link and dual telescopic forks, both of which allow the two front wheels to lean into corners.

This makes the Yamaha Tricity an absolute joy to ride always.

5. Impressive Fuel Economy:
Thanks to Yamaha’s Blue Core technology, the Tricity doesn’t guzzle fuel.
The model’s 155cc four-stroke engine produces enough power to propel you quickly across the city. Still, it sips fuel, demonstrating Yamaha’s commitment to giving performance using less fuel.

If you’re looking for an economical way to move around, the Yamaha Tricity is an ideal option.
