Doc, I’m thinking of buying a new Ultra and fitting it with a 120R motor. Have you heard of anyone using the 120R for long hauls and sitting on it for a 10-15 hour day? Can you advise me as to the longevity of it? I would appreciate your comments.

John, I discussed your situation today with a buddy of mine who works for Harley-Davidson, explaining to him why you were thinking of going this way.

He totally endorses the 120R and said, “The 120R is probably the best value for money when you want extra grunt. They are great in the touring bikes because of the extra horsepower and even better on the open road. It would be a good choice. We sell a lot of 120R engines.” Long hours and high miles are not a problem with these engines; just follow the recommended maintenance schedule.
