Introduction to the Husqvarna 701 Supermoto

The Husqvarna 701 Supermoto is a high performance single cylinder motorcycle that was introduced by Husqvarna Motorcycles in 2016. Part of Husqvarna's neo-retro street bike range, the 701 Supermoto combines a modern 693cc single cylinder engine with old school supermoto styling. With a lightweight chassis and upright ergonomics, the 701 Supermoto is designed for maximum fun both on and off-road.

Overview of the Husqvarna 701 Supermoto

Here are some key features of the Husqvarna 701 Supermoto:

  • 693cc single cylinder 4 stroke engine producing 74 horsepower
  • Six speed transmission with PASC anti-hopping clutch
  • Chromium-Molybdenum rigid steel trellis frame
  • WP USD 48mm front forks and WP monoshock rear suspension
  • Brembo brakes with 320mm front and 240mm rear discs
  • Spoked wheels in 17 inch front and rear
  • Slim, compact ergonomics for easy handling
  • Striking styling combining modern and retro elements

With its upright seating position, wide handlebars, and spoked wheels, the 701 Supermoto takes inspiration from dirt bikes of the 1970s. However, under the retro-styled bodywork lies thoroughly modern engine and chassis technology. The result is a bike that handles like a nimble supermoto racer, while still being suitable for daily street riding.

Engine Performance of the 701 Supermoto

Powering the 701 Supermoto is a fuel injected, 693cc single cylinder engine with a dual overhead camshaft design. This advanced engine generates a strong 74 horsepower at 8,000 rpm, with plenty of torque available across the rev range. Weighing just 61.5 kg, the compact single cylinder motor contributes to the bike's excellent handling.

Some key features of the 701 Supermoto engine include:

  • Liquid cooling for consistent performance in all conditions
  • Electronic fuel injection with 46mm throttle body
  • Forged box-type piston for strength and low vibration
  • Crankshaft designed to minimize vibrations
  • Two balancer shafts to further reduce vibration

This sophisticated single cylinder provides smooth, reliable power delivery on the street or when blasting around a racetrack. The PASC anti-hopping clutch prevents rear wheel hop during aggressive downshifts, allowing hard braking and downshifting for corners.

Exhaust System Options for the Husqvarna 701 Supermoto

One of the great things about the Husqvarna 701 Supermoto is that it comes stock with a premium Akrapovic exhaust system. This top brand slip-on silencer gives the 701 a throaty, powerful sound while still meeting noise regulations. However, some owners choose to upgrade or replace the stock muffler to get more performance or a different exhaust note.

Aftermarket Exhausts from Leading Brands

Here are some popular exhaust options from leading manufacturers:

  • Akrapovic Slip-On Line: Akrapovic's Slip-On Line exhaust system is an upgrade from stock featuring titanium and carbon fiber construction to save weight. It provides a deep, resonant sound along with minor performance gains.
  • Arrow Slip-On Exhaust: Arrow makes a range of slip-on exhaust cans to replace the stock muffler, crafted from carbon fiber or titanium. These Arrow exhausts offer different sound levels from modest to aggressive.
  • SC-Project CR-T Slip-On: The CR-T slip-on from SC-Project features a carbon fiber sleeve and titanium internals, providing a 11% weight savings over stock. It produces a mellow, pleasant tone.
  • LeoVince LV 10 Slip-On: LeoVince's LV 10 features a removable dB killer allowing owners to adjust the sound level. It's a full system crafted from stainless steel with carbon fiber end caps.

These aftermarket exhausts provide aesthetically pleasing systems with a range of sound options from subtle to wide open. While performance gains are modest, reducing weight and adding an attractive exhaust can enhance the 701 Supermoto's fun factor.

Considerations for Choosing a 701 Supermoto Exhaust

Here are some factors to think about when choosing an aftermarket 701 exhaust:

  • Sound level - Does the exhaust have removable dB killers or inserts to adjust volume?
  • Materials - Lighter materials like titanium and carbon fiber reduce weight.
  • Performance gains - Generally just a few HP; focus is more on sound.
  • Weight savings - Important for nimble handling; look for lighter exhausts.
  • Price - Aftermarket systems range from around $500 up to $1200.
  • Emissions laws - Ensure the exhaust system still meets any required regulations.

Speaking to other Husqvarna 701 owners can provide real world feedback on available exhaust options. Overall, the 701 Supermoto is an outstanding machine right from the factory, so any exhaust changes are just the icing on the cake.

Maintaining and Modifying the 701 Supermoto

While the Husqvarna 701 Supermoto delivers thrilling performance straight from the showroom floor, owners can further enhance their bike through careful maintenance and select upgrades.

Maintenance Tips for the 701 Supermoto

To keep a 701 performing at its best, owners should follow the recommended factory maintenance schedule in the owner's manual. Some key maintenance tasks include:

  • Regular oil changes with synthetic oil per the owner's manual
  • Cleaning the air filter periodically and replacing as needed
  • Checking and adjusting chain tension every 500 miles
  • Changing the coolant every 2 years
  • Checking spoke tension on the wheels
  • Inspecting brake pads and rotors for wear

Many owners also choose to upgrade common wear items for increased performance and durability:

  • Installing sintered brake pads for improved braking
  • Upgrading the clutch springs for a lighter clutch pull
  • Adding crash protection like frame sliders and swingarm spools
  • Fitting a steel braided front brake line for better brake feel

Popular Modifications for the Husqvarna 701

Here are some other common mods owners perform on the 701 Supermoto after the break-in period:

  • Installing an aftermarket exhaust system
  • Tuning the ECU with a fuel controller or custom mapping
  • Upgrading the suspension with stiffer fork springs or rear shock
  • Adding wider handlebars or adjusting bar position
  • Fitting sticky sport tires for racetrack days
  • Removing unnecessary street equipment to reduce weight

With the right combination of maintenance and upgrades, Husqvarna 701 owners can take the Supermoto's performance to an even higher level. But even in stock form, it's an incredibly fun and capable motorcycle.


The Husqvarna 701 Supermoto delivers a thrilling blend of contemporary performance and retro style. With a muscular 693cc single cylinder engine housed in a lightweight, nimble chassis, the 701 is a rippingly quick motorcycle equally at home on city streets and twisty backroads. While the stock Akrapovic exhaust provides a great starting point, many owners choose to install an aftermarket slip-on muffler to put their own personal touch on the bike's look and sound. With proper care and enhancement, the Husqvarna 701 Supermoto provides huge smiles per mile for years to come.


Does the stock Husqvarna 701 Supermoto exhaust limit performance?

The stock Akrapovic exhaust offers good performance while meeting noise regulations. Upgrading to an aftermarket system only provides modest horsepower gains, usually less than 5hp. The main benefits are reduced weight and a different exhaust note.

What's the best 701 Supermoto exhaust for sound?

Arrow and SC Project make slip-on cans that give the 701 a really aggressive, loud exhaust note. LeoVince and Akrapovic offer systems with removable dB killers so owners can adjust the volume. Each brand has a unique tone.

How much does it cost to upgrade the exhaust?

Aftermarket exhaust systems range from around $500 to $1200 depending on the materials and brand. More affordable options use stainless steel while premium systems from Arrow, Akrapovic, etc. use exotic materials like carbon fiber or titanium.

Does changing the exhaust require remapping the ECU?

Not necessarily. While many owners choose to tune the ECU after an exhaust upgrade to maximize performance gains, the 701 will run fine with just a slip-on muffler change without remapping.

Do all exhaust options meet emissions regulations?

No, some exhausts are designed for closed course use only. Make sure to check that any exhaust system meets noise and emissions laws for street legal use in your region. Most slip-on cans meet requirements.
