We at PowerSportsGuide have compiled all you need to know into this Yamaha SXR 700 review!
Yamaha SXR 700 Review
Yamaha introduced its high-performance SXR line in late 1999 and marketed it from 2000 through 2003. This popular family consisted of three models, which were as follows:
- Yamaha SXR 700 triple (SX700R)
- Yamaha SXR 600 triple (SX600R)
- Yamaha SXR 500 twin (SX500R)
It’s a lesser-known fact that the official model names of these sleds were SX 700 R, SX 600 R, and SX 500 R, but they were more commonly known as SXRs.
Unlike the sportier SRX, these models were built on the more comfortable SXR chassis.
The most famous sled in this line was arguably the flagship 700cc model, and with good reason.
Powered by a liquid-cooled, single-piped, 698cc, 2-stroke, 3-cylinder engine, the SXR 700 offered a remarkable 115 HP!
This machine was not only extremely powerful, but it offered excellent handling as well. Unlike the “drag racer” SRX line, the SXR family utilized an outstanding long-travel rear suspension, which offered comfortable rides even on moguled trails.
According to the reviews, the SXR 700 was probably the best-handling trail snowmobile of its time.
Standard features included the adjustable thumb and hand warmers, hydraulic brake system, mechanical parking brake, headlights powered by a 300W magneto, tunnel protectors to keep studs away from the tunnel, and the unique Throttle Override System (T.O.R.S.).
The SXR 700 also had a 15” wide, 121” long rubber track with 0.92” lugs.
What is the Difference Between a Yamaha SXR and SRX?
Although these models are often confused, the Yamaha SRX and the SXR were two completely different sleds. The latter was officially called SX 700 R, but it was commonly known as the SXR 700. The main differences between the SXR and SRX models were their engine, suspension systems, and body.
Although both machines utilized a 2-stroke, 3-cylinder engine, these power sources were completely different.
The SRX 700 was powered by a triple-piped, 696cc engine with power valves, ensuring more power and higher top speeds than the SXR.
In contrast, the SXR 700 utilized a single-piped, 698cc engine with no power valves that cranked out about 20-30 less horsepower than the SRX.
So, in a nutshell, the significant differences between the Yamaha SRX and SXR are as follows:
- Yamaha SRX: more powerful three-piped engine, better top speed and acceleration, short travel suspension, different belly pan and hood, Yamaha Pro Action System chassis.
- Yamaha SXR: single-piped engine, less HP and top speed, fewer engine issues, “SXR” chassis, more comfortable ride due to long-travel rear suspension (11.5”).

Yamaha SXR 700 Problems
Even if the SXR 700 was considered the “hottest sled” in the 2001 Yamaha lineup, it had some weaknesses.
One of the biggest problems with the Yamaha SXR 700 was the lack of a reverse system.
Let’s face it, having a reverse on a snowmobile is a game-changer in many situations. This is why you will find an aftermarket reverse kit on many vintage SXR sleds!
Another common complaint against the SXR 700 was T.O.R.S issues. Yamaha’s Throttle Override System, known as T.O.R.S., was a safety feature designed to shut off the engine in case of a malfunction with the carbs or the throttle cable.
Although this technology was a revolutionary idea, this particular unit was prone to producing various malfunctions, resulting in many headaches.
Last but not least, don’t forget that the SXR 700 wasn’t a lightweight machine, so it was primarily recommended for trail riding.
