Introduced for the 2018 model year, this small-displacement motocross machine marked Yamaha’s push to give younger riders a true competition bike rather than a beginner playbike. Yamaha positioned it as an entry point into the brand’s off-road racing ladder, using the same YZ family identity and styling cues associated with the company’s adult motocross models. The nameplate was launched in 2018 for the Japanese market as a purpose-built kids’ racer, and it has remained part of the off-road competition lineup since then.
The model’s historical significance comes from how it filled the gap between Yamaha’s long-running youth off-road offerings and its full-size YZ motocrossers. It was developed around the idea of giving child riders a machine with genuine race-bike character, while keeping the package compact enough for smaller riders. Yamaha’s launch materials emphasized that it was aimed at first-time competition riders and that it shared family design language with the larger YZ range, reinforcing its role as the junior gateway to the brand’s motocross program.
Because the model is still in production, there is no final model year to record. There is also no evidence of a discontinuation and later revival, so it should be treated as a single continuous production run from its 2018 introduction onward.
