Yamaha Mountain Max 700 Review

The first Yamaha Mountain Max snowmobiles hit the snow in the 1996 season. However, these sleds were just variants of the popular VMAX series and not part of the “real” Yamaha MM (Mountain Max) family.

The all-new 2-stroke Yamaha Mountain Max (MM) line was marketed from 1997 through 2004 and consisted of three different models:

  • Yamaha Mountain Max 600 (MM700) –  Manufactured: 1997-2002
  • Yamaha Mountain Max 700 (MM700) – Manufactured: 1997-2004
  • Yamaha Mountain Max 800 (MM800) Manufactured: Only in 1997

For some reason, the most powerful Mountain Max 800 was available only in the 1997 season, but the most popular 700s remained in production until 2004.

Like every other Yamaha sled of the era, the Mountain Max models were also known for their high-performance and reliable engines. Therefore, they instantly became popular among off-trail riders.

The Yamaha Mountain Max 700 engine was a 698cc, 2-stroke, triple that cranked out about 115 HP at 8300 RPM. This liquid-cooled unit featured three Minuki TM33 carburetors and a manual start.

Unlike the more sporty SRX engine, this power source was single-piped, which resulted in less HP and simpler exhaust music. To boost the performance and the sound of the machines, many owners installed “triple pipe kits” on their 700s.

Besides its tremendous power, this Yamaha sled was also well-known for its good fuel consumption.

Just like its high-performance engine, the chassis and the other features on the Mountain Max were engineered for mountain rides.

The early models were propelled by a 136” x 15” x 1.5” track, which was replaced with a 141” x 15” x 2” unit for the 2000 season.

Besides the longer track, the 2000 Mountain Max 700 saw many other upgrades like the advanced ProAction Mountain rear suspension system, tapered tunnel, better approach angle, and a mountain strap.

Thanks to these innovative features, this sled had outstanding climbing abilities and could handle the hardest mountain trails with ease. On the other hand, the MM 700 wasn’t actually designed for jumping or huge cliff drops.

After the 2004 season the Mountain Max 700 was ceased and the entire MM family disappeared from the market.

But to the delight of many fans, in 2021 Yamaha reintroduced the popular 2-stroke Mountain Max series!

Yamaha Mountain Max 700 Problems

But let’s face it, every sled has its weak points, and the Mountain Max 700 was no exception.

In a nutshell, the most common problems with the Yamaha Mountain Max 700 were as follows:

  • Defective front suspension ski columns (Recall on the ‘97 and ‘98 models)
  • T.O.R.S. malfunctions
  • Water pump sealing issues (on the early models)
  • Lack of a reverse gear and passenger seat
  • Lack of an electric start

Let’s start with the recalls. Yamaha issued an official recall on the 1997 and 1998 Mountain Max 700 models due to their defective ski columns on the front suspensions.

Another common problem with the Mountain Max 700 was the T.O.R.S malfunctions, but this system could be fixed relatively easily. At least this model didn’t suffer from Smart Carb issues, which was a common problem on the 600s.

Finally, don’t forget that this sled was designed to carry only one rider and came without reverse gear and an electric start.

Apart from these, the Mountain Max 700 was one of the most reliable and dependable mountain snowmobiles around the Millennium.

Yamaha Mountain Max 700 Top Speed

Therefore, the top speed of the Yamaha Mountain Max 700 was about 85-90 mph under ideal conditions. In contrast, other triples like the SRX 600 reached a whopping 105-110 mph, while the SRX 700 topped out at 110-115 mph.
