The new Indian Thunder Stroke 111 engine is running and I have seen it. Polaris Industries, a $3-billion-a-year corporation, bought the King's Mountain Indian business in April, 2011. What I have seen is an entirely new, free-standing design, sharing nothing with previous Indian revivals or... 

Last column, Skidmarks – (Excelsior-Henderson) X Factor, I related the curious case of die-hard Excelsior-Henderson fans, men and women who love their motorcycles and loyally keep them running, year after year. I chatted with a few of them to get an idea of why they liked the big V-Twins so...
