Ducati Streetfighter V4 S 2021

Ducati Streetfighter V4 S 2021

The problem of the Streetfighter V4 S with Euro4 engine, namely no power in the lower rev range but explosion in the upper rev range, has been largely rectified with the update to Euro5. Although the disgusting 208 hp are still only available at 13,000 rpm, the SF V4 S now also works acceptably at lower revs. The electronic Öhlins suspension is at its best and the brute Brembo Stylema stoppers again celebrate the penchant for the racetrack. Ergonomics and handling are also basically good, but on the racetrack you would wish for lower handlebars because of the awesome power. A perfect poser bike that also works on the country road, and on the racetrack anyway. Only the too-loud sound should be curbed a little.

The most powerful naked bike ever

good ergonomics

superb, electronically adjustable Öhlins suspension

brute Brembo Stylema brakes

full electronics package

handsome, distinctive look.

very expensive

loud exhaust sound

full power only in the upper rev range

KTM 125 Duke 2021

KTM 125 Duke 2021

Even in the Euro 5 version, the KTM Duke 125 is the motorbike to beat in the A1 class. Superior equipment, potent engine, good chassis, great display and fun Supermoto mode make not only the heart of 16-year-olds beat faster. The looks polarise, but let the observer clearly recognise the smallest Duke as such. The Duke 125 is not cheap, but it is worth the price.

lively engine

super-agile handling

Supermoto mode as standard

mature chassis

top brakes

sharp TFT display

connectivity (optional)

Optics not to everyone's taste

price high for a 125cc bike
