2018 Vitpilen 401 - Pros & Cons
Strengths
-
⚡
Strong power output: With 43 hp @ 9000 rpm and 37 Nm @ 7000 rpm of torque on tap, the Vitpilen 401 is no slouch for its class.
-
🔧
Fuel injection: Fuel injection means consistent cold starts and clean throttle response without the fussiness of a carbureted setup.
Considerations
-
📏
Tall seat height: At 835 mm, shorter riders will likely be on tiptoes at a standstill - worth sitting on one before you buy.
-
⛽
Modest fuel capacity: Range between stops is limited by the 9.5-litre tank - plan fuel stops accordingly on longer routes.
-
⚙️
Chain final drive upkeep: Budget time for routine chain maintenance - it's cheap to replace but needs consistent attention to avoid premature sprocket wear.
Wear Points & Servicing Notes
Cooling system servicing
Vitpilen 401's Liquid cooled setup is low-maintenance provided the coolant interval is kept - old, acidic coolant is the main cause of long-term corrosion in the water passages.
Fuelling & injector care
The fuel injection on the Vitpilen 401 needs little beyond good fuel and periodic use of an injector-cleaner additive - no jetting or float-bowl maintenance to worry about.
Brake disc and pad wear
Braking up front comes from Single 320mm disc, 4 piston floating calliper - solid stopping power, with disc and pad wear best checked on the same schedule as tyre changes.
Suspension condition on used examples
The Vitpilen 401's suspension runs 43mm WP upside-down forks at the front. The rear uses WP monoshock. Fork-seal condition and rear linkage play are the two things worth checking before buying used.
Final drive maintenance
The Vitpilen 401 uses chain final drive, which is cheap to replace but needs regular cleaning, lubrication and tension checks to get a full service life out of the sprockets.
Frame & chassis check
Built around a Steel trellis frame, powder coated, the Vitpilen 401's chassis is straightforward to inspect: look for corrosion, cracks or repair welds around stress points like the head-stock and swingarm mounts.
Vitpilen 401 - Buying & Maintenance Guide
What to check before buying
Before handing over money for a used 2018 Husqvarna Vitpilen 401, cover the fundamentals: service book and oil change history, chain and sprocket wear, and any sign of oil weeping around the casings. Cold-starting it yourself tells you a lot - a healthy Vitpilen 401 should catch quickly and settle into a smooth idle.
Oil and filter changes
Nothing protects a Vitpilen 401's engine like disciplined oil changes - stay on the manufacturer's schedule (roughly every 6,000 km or annually). Match the viscosity grade to what the owner's manual specifies, not what's cheapest.
Fuel system care
Fuel injection on the Vitpilen 401 needs little attention beyond decent fuel and an occasional system-cleaner additive. Anything left standing for three months or more should have its fuel drained and replaced before it varnishes the injectors.
