5 Most Common Problems with Yamaha VMAX

Introduced in 1985, the Yamaha VMAX singlehandedly created the power cruiser category.

It delivered mind-boggling speed and power, leading to the moniker “Mad Max.” The VMAX has remained in production for 35 years and has become one of Yamaha’s most iconic models.

The VMAX is a good choice for anyone; however, it has a few flaws, which we’ll examine in this article.

To come up with this list, we scoured various forums to get complaints from real-life owners of this model.

Based on our research, here are the most common problems with the VMAX models:

1. Bike Stutters and Stalls

According to some users, the Yamaha VMAX bikes often stutter and lose power on occasions, completely stalling.

According to them, the bike acts as if there’s no fuel left in the engine, and the ‘low fuel’ light warning light stays on. However, the owners say the problem occurs even when the tank’s full of fuel.

Moreover, riders often have trouble starting their bikes, cranking multiple times before they can run properly. This starting problem is even more pronounced during cold weather. Also noteworthy is that this problem is common to older carburetted models, i.e., those using carburetors.

From our research, the major cause of the problem is a clogged fuel line/pump. The fuel pump transports gasoline from the tank to the engine.

Faulty fuel lines will reduce fuel supply to the engine, and can affect performance negatively:

  •  It will be difficult to start your bike.
  •  Your engine will sputter and may stall.

Since most faulty fuel lines are a result of dirt that clogs the system, a system cleaner can solve the problem. System cleaners are available at most large retail stores.

Adding system cleaner liquid to your fuel tank will clear residue that may be blocking your fuel lines.

2. Malfunctioning Oil Pump

The oil pump on a bike circulates lubricant throughout the engine.

A faulty oil pump can lead to anything from an increase in the motorcycle’s temperature to extensive engine damage.

Yamaha VMAX bikes, particularly those released between 2008 and 2011, tend to have malfunctioning oil pumps. On affected bikes, the oil pressure can rise to excessively high levels.

If such happens, the oil may stop pumping through the engine. This can lead to the engine stalling or failing to start. In severe cases, it may lead to serious damage.

Yamaha issued a recall for the bikes affected by the problem (2008-2011 models). It required dealers to replace the faulty oil pumps with new units, free of charge.

If you happen to buy a used VMAX with this problem, the only solution is to buy a new oil pump unit.

3. Faulty Wiring Loom

Owners of VMAX bikes, especially older models, have experienced issues resulting from faulty wiring looms.

In a particular case, the ground joint connector (a part of the wiring harness) overheated to the point of deformity.

Faulty grounding connections on a bike will cause the ignition system to fail and affect engine performance.

Other symptoms associated with this problem include:

  1. Engine surging while accelerating: The engine’s RPM fluctuate wildly, even though you’re not changing gears. In a situation like this, your bike may experience lurching or jerking motions.
  2. Stalling/cutting out power: If the grounding connection for the motorcycle is bad, your bike may lose power and stall while you’re riding.

Yamaha once issued a recall for bikes affected with this problem, replacing the wiring harness at no cost to owners.

However, if your bike isn’t under warranty, you may have to buy a new wiring loom.

4. Poor Fuel Economy

Since its inception in 1985, the Yamaha VMAX has maintained a reputation as a big, brawny motorcycle with loads of performance.

Consider the 2019 VMAX model: it comes with a powerful 1679cc engine that delivers around 123 pound-feet of torque.

However, this performance often comes at the expense of fuel economy. The 2019 model gets, on average, an estimated 32 MPG. By comparison, its rival, the Ducati Diavel, comes with an estimated 44 MPG.

While the VMAX has a lower price tag, those fuel costs can quickly add up if you’re not careful.

Asides its engine, size/weight is another likely cause of the high fuel consumption on the VMAX bikes. For instance, the 2019 VMAX has a curb weight of 638 pounds.

That’s up to a hundred pounds more than its closest competitor, the Ducati Diavel. It’s a no-brainer that the heavier a bike is, the more fuel it will consume.

5. Average Ride Quality

Over the years, the Yamaha VMAX has emphasized performance over anything else.

It was the fastest bike in the world months after its debut in 1985. But things have changed since that time.

Nowadays, riders want bikes comfortable for both city riding and long-distance touring. On both fronts, the VMAX fails to deliver.

Compared to a similar model e.g., Ducati’s Diavel Strada, the VMAX offers less in terms of rider comfort.

The Diavel has wider, swept-back handlebars and lower, forward-leaning footpegs, making for a relaxed and laid-back riding posture. In contrast, the VMAX seat design forces the rider to crouch while riding, meaning more backaches.

Simply put, the VMAX isn’t the bike you can go touring with. In fact, one common complaint among VMAX owners is that the rider and passenger seats are both uncomfortable. In comparison, the Diavel has a plush pillion seat and even features a backrest for added security.

If you want a high-performance straight-liner, the VMAX is a suitable choice. However, if you want a comfortable daily driver or long-distance tourer, we’d advise buying another model.

Pros of Yamaha VMAX

Here are some merits of the VMAX:

I. Impressive Performance

In terms of performance, only a few motorcycles can compete with the VMAX.

It features a liquid-cooled, 16979cc, V4 engine that offers copious amounts of power.

To illustrate: the 2020 model delivers 200 horsepower at just 9000 RPM and 123.2 pound-feet of torque at 6,500 RPM.

With such specs, it’s not surprising that the VMAX is among the most powerful motorcycles on the market.

II. Performance-Enhancing Technology

Yamaha’s engineers outfitted the VMAX with advanced technologies, which help improve the overall riding experience.

A good example is a slipper clutch found on modern VMAX bikes.

Not only does the slipper clutch improve performance, but it can also prevent rear-wheel lockup in the event of engine seizure or transmission failure.

Other useful features on the VMAX motorcycles include:

  1. Wave-style brake discs: Compared to regular round brakes, wave-style brakes wear out less rapidly. This will reduce long-term costs and ensure your brakes stay in excellent condition for longer.
  2. Anti-Lock brake system (ABS): The VMAX features Yamaha’s linear-controlled three-position ABS system. This provides improved control while braking on wet or slick surfaces.
  3. Adjustable front and rear suspension: The adjustable design allows riders to change suspension settings to match their weight, load, and road conditions.
  4. YCC-T Fly-by-wire throttle: This provides exceptional throttle response and throttle control and makes for a responsive riding.

III. Lightweight Chassis

Made from aluminum, the bike’s lightweight frame helps improve overall speed and handling capabilities.

It also allows for balance and stability, even at higher speeds.

IV. Reliability

Being a Japanese-made bike, we are not surprised at the reliability of the VMAX.

Even though it has been in production for over 35 years, the motorcycle has witnessed few recall actions.

The VMAX models have very high build quality, which allows them to handle long-term use without breaking down.

V. Good Handling Capability

Early VMAX models were berated for poor handling and cornering ability.

However, newer models have improved in that aspect and offer superb handling ability.

The lightweight aluminum chassis places the engine low and forward for centralization, helping the bike handle corners and straight roads well.

Now, you can take a VMAX for a canyon-carving ride and watch it attack corners like a champ.

Cons of Yamaha VMAX

Here are some shortcomings of the VMAX:

  1. Bike Stutters and Stalls
  2. Malfunctioning Oil Pump
  3. Faulty Wiring Loom
  4. Poor Fuel Economy
  5. Ride Quality Is Average
