Sherco unveils 2021 enduro range

French dirt bike maker Sherco has revealed its 2021 four-stroke and two-stroke enduro range with significant upgrades, rather than a ground-up redesign. There are two ranges, the Enduro Racing are the standard models while the Enduro Racing Factory are the higher-end bikes with upgraded components in many ares.

  • Titanium Akrapovic Exhausts systems for 4T Factory models
  • New ignition coil control unit improves intensity and durability of sparkplugs (250/300 SE)
  • Tilt sensor (250/300 SEF)
  • New connecting rod bottom end bearing to help reduce stalling (250/300 SEF)
  • New crankcase design (250/300 SEF)
  • Lower compression combustion chamber (300 SEF)
  • New intake and exhaust camshaft profile (300 SEF) 
The 250 and 300 smokers are most popular

Engine updates for the 250cc and 300cc two-strokes

The new range of Sherco Enduro models, SE for two-stroke and FE for four stroke, include SE 125, 250 and 300 two-stroke and SEF 250, 300, 450 and 500 four strokes. 

Engine changes in the 250/ 300

Weight savings of 1.2kg on the 250 and 300 SE models come via a 50% lighter transmission gear and axle, lighter gear selector barrel, redesigned clutch and a new cylinder head. The cylinder head is also running lower compression and results in higher rpm without losing any low-end performance. 

Aiming at reducing vibration to aid reduction of arm pump while riding, the 2021 250 and 300 SE two-stroke engines feature an anti-vibration balancer.

The range goes up to 500cc four-stroke

Both of the bigger capacity SE two-strokes also have improved gearbox selectors, new gear ratios and are lighter by 600g. The secondary drive shaft and gearbox output shaft are now standardised across all SE models. 

The 250/ 300 factory is one sweet machine!

A new Athena ignition coil control unit improves intensity and durability of the spark on 250/300 SE models. This works in conjunction with the two ignition maps, hard and soft on the handlebar switch, which offers riders a five-horsepower difference depending on terrain. 

Overall it is an impressive change in the 250 and 300 models to have more power, better power delivery and over a kilo (over 2.5 pounds) less weight.

The 250 and 300 smokers are hugely popular

The four-strokes changes 

Sherco ‘s plan is to extend engine life, reduce engine noise and unleashes more power at higher rpm. A new connecting rod bottom end bearing which is now a plain bearing for 2021 replaces the old roller bearing. There’s also a new connecting rod helping reduce stalling which in turn means a slight change to the engine cases to adapt and allow better circulation of oil inside. 

The balancer shaft is smaller diameter, further reducing weight internally and in rotating mass. Like the 250 and 300 two-strokes, the 300 SEF also has a new combustion chamber with lower compression to make engine response smoother. There are new intake and exhaust camshaft profiles, to increase power at higher revs.

The 250 and 300 SEF four stroke models have a tilt sensor under the seat. The aim is for the engine to shut down in the event of a crash.

Nice Akra bling

Akrapovic Titanium exhaust

The 250 and 300 SEF 4T models get the latest generation factory exhaust systems from Akrapovic. The full titanium system improves higher rpm performance yet reduces noise.

The 125 is a flier!

Changes to the 125 and 450/500 engines

 The 450/500 SEF engine has a host of gearbox changes with a new anti-vibration balancer sprocket, starter pinion and oil pump gear to reduce weight.  The 125 SE engine has an updated the crankshaft.

Across all bikes there are new graphics and Michelin tyres as standard.
