I'm not a mechanic but I just don't see riding redline or near redline any good for the engine. I would assume it would just shorten it's life and to a 30 year old bike? I wouldn't be comfortable with that. Now when I had a 250 I was riding it constantly in the 8-11k but that's where the powerband is and it's not like I was going to keep the bike forever.
I have no experience with that bike, but my 1982 450 Honda didn't need to work that hard on the highway (after cleaning the carbs, adjusting valves etc). Why is the bike working so hard at 100? When I got rid of the 450 it would still be accelerating through 150 (indicated). Before I read the bike type, I thought he was talking about a 125.
Drumstyx, bike speedos are notoriously optimistic, 100 indicated may only be 90, be careful you don't get run over.
I thought it was a 125 he was talking about as well. My early 70's CB175 pulled harder than this 400. My '75 Yamaha 500 twin would run at 80mph for hours, nowhere near the redline.

A lot of cars and motorbikes redline then the limiter cuts in and your engine dies, then picks back up to normal riding. If I remember correctly if you exceed the redline and your engine is running you get valve bounce. Not good. Mechanics please verify.
Good news everyone! I took the highway to work today, and the sections that weren't stop n go were 100km/h (measured by gps on phone mounted on tank bag) at 5-6k! This was in relatively still wind, and when it was down as low as 5k it was downhill, but I definitely felt better than last time. I'll keep an eye out for how it feels it harsher conditions, but as it is, I think 6k is fantastic (and not WOT this time either!)
Higher revs equal higher stresses on moving parts. Your engine is designed to operate at anything up to redline. Unless there is an internal fault inside your engine already you can run at redline all day. I have done this for years on many bikes with no issue. For anyone who tells you the engine will blow for no reason other than high revs they are spreading rumors and ignorance only.
Good point, actually. I was more thinking about the fact that it was so weak at WOT to only just be able to hit 6500rpm and simply not push harder. I actually tried this morning, and 100 was a total breeze. It must have been the strong winds that were problematic last time, but 6500 was a solid 105 this morning, and I had room to go on the throttle.
I should have mentioned, that was traffic speed. Here in Hamilton, the highway speed limit is 90 too. 7000 would be right about 110-115, which is entirely reasonable.
