Triumph Motorcycles America is reporting today a healthy 15% gain in its sales over Q1 2017, compared to the same time period from last year.

Triumph doesn’t breakout its sales figures by model, but we can expect that most of those gains come from the company’s “heritage” lineup, which has seen the addition of five new post-authentic motorcycles for the 2017 model year.

Of course, anyone who has followed the Triumph brand in the United States will greet this news with an ounce of skepticism, as the British marque has earned itself a reputation for being less than forthright with its sales figures.
