Having just seen the TR650 for the first time this past weekend, I noticed the oil lines immediately. I have a tendency to fly my Bonnie down dirt/gravel roads, and have paid the cost on several oil coolers. I'm about to replace another.
The whole point of me buying a Terra is to go even faster down those roads, and with a lot less regard for the bike itself. Those exposed oil lines are in a very dangerous place.
