My Yamaha bike

It seems like you're referring to the Yamaha YBZ-DX. However, as of my last update in January 2022, there isn't a specific model called YBZ-DX in Yamaha's lineup. It's possible that it's a newer model introduced after my last update, or it might be a regional variant or a concept model. If you can provide more information or clarify, I'd be happy to assist further!
