Pros and Cons in comparison

Pros and Cons in comparison

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

Yamaha MT-09 SP 2021

Yamaha MT-09 SP 2021

The Yamaha MT-09 SP is based on the really well-done MT-09. In 2021, a particularly fine vintage! But the upgrade goes one better! The high-quality chassis provides a great compromise between riding comfort and sportiness.

Upright, comfortable seating position

Well-tuned chassis

Mappings and traction control are quick and easy to adjust

High-quality workmanship

Lovely details

Great tuned engine

Great acceleration and lots of pressure in the relevant rev range.

Horn mounted in a crude way

poor display
