With motorcycles now having to meet EU4 emission rules, there has been an on-going homologation process at Spirit Lake to ensure Indian offers the best products possible.
As such, for 2018, all of the Thunder Stroke 111 engined models have a 15hp increase in power and a 15Nm increase in torque (models now have 84hp and 150Nm).
Indian Motorcycle’s International Product Manager, Ben Lindaman commented: “Indian’s engineering team achieved the increase in power and torque by removing intake restrictions, equipping the bikes with better flowing exhaust, and optimising the calibration for this setup. The results are a substantial 21% power increase and an improved throaty exhaust tone as well.”
