Turbo motor reliability

Hey Sarah, when you say "turbo motor," are you referring to the Brose Drive S Mag (sometimes called Turbo in Specialized models) or just high-power motors in general? If it's the Brose, they're generally super reliable, but I've personally seen a few need a belt replacement after about 5,000 hard miles. The key to any motor's lifespan is usually keeping it dry and avoiding massive gear shifts under max power.
