Yamaha Motor USA is seeing a resurgence in its motorcycle market, with Yamaha posting a healthy 28% sales increase in the North American market, for the first-half of 2015.

The sales boost comes due to the release of the Yamaha YZF-R1, and likely aided by the Yamaha FJ-09, and Yamaha FZ-07 – all of which debuted to rave reviews from the moto-press.

Overall, Yamaha’s motorcycle business is seeing good growth, up another 14% in the European markets (boosted by the MT-09 Tracer), for a total increase of 7.6% in revenue (¥36.8 billion) across all markets.
