All indications are that Triumph is set to fill the hole in its cruiser line-up between the 865cc parallel twins at the low end, and the huge Rocket III (displacing nearly 2,300cc) on the high end.
A 1,500cc parallel twin is expected to power the new bike, and styling should mimic classic Triumphs — similar to the current Bonneville. Expect an announcement, and an unveiling, next month in Europe.
