A couple of weeks back at the Royal Enfield Club of Australia Winter Rally in Broken Hill I was impressed to see that UCEs - the Royal Enfield unit construction engine Bullets - had come from all over the place, at highway speeds, without a hitch. The old Bullets such as mine will blow up if you do highway speeds all day, and might blow up anyway even if you stick to 80kph. Well I just read of one fellow doing a 1000miles-in-a-day challenge on his UCE and it held up fine! It actually did 1760kms in 20hrs. At 130kph. http://www.enfieldmotorcycles.com/forum/index.php/topic,14942.msg160517.html#msg160517 Sure, a few things went wrong. But they were minor in my book (witness that he fixed them on the road) and you can expect challenges from a big single ridding for almost 2000km at 130kph, and in the budget-priced case of the Royal Enfield it's fantastic.
