Evaluation

Jeff2A Model 2026

A pleasant surprise, since sports bikes in this displacement class have become very rare on the French market.
And with a model like this, it almost feels like we’ve gone back to the golden age of the 1980s, with sporty two-strokes like the Yamaha 350 RDLC or Honda NSR 400, which produced roughly the same power back then.
It remains to be seen how a QJ Motor bike holds up over time, but at first glance, “Made in China” has made some serious and rapid strides in quality and performance in a very short time! All while remaining very attractive in terms of price!!
And in terms of aesthetics and finish, we’re now on par with Japanese and European standards! 04/13/2026 19:24 Rating : 5/5 Respond to Jeff2A

Alain81 Model 2026

A strong competitor to the 400cc Kawa ZX-4R, which sells for... €3,000 more!
That's a blow to the Japanese bike! 03/14/2026 10:53 Rating : 5/5 Respond to Alain81
