Bonne is up to 6000 + miles, got it early Feb. And pretty much ride it every day. Pushing the limits during the weekend and riding more highway. So what's good for the bike and when do I just hold back to keep my ride in top shape.

Interesting question. I don't have an answer for the Bonnie. In older BMW manuals, they would provide all kinds of specs for which the Germans are famous. One that was interesting was "maximum rpm", say 7500 followed by "maximum permissible continuous rpm, say 7250. In other words, they were saying it was ok to put one of their bikes on the autobahn and run it for hours on end at 7250 rpm.

I don't know of any data like this that is available for our Bonnevilles.

A good question Anglen, and an interesting "maximum rpm vs. maximum permissible continuous rpm" observation Bob. I'm guessing that, as there have been very few reports of engines blowing up with the higher rpm boxes fitted, that the standard limit of 7200 (I think, off hand) may be fairly sustainable. Having said that, I'm quite reluctant to hold the throttle wide open too long - partly because most of the roads here in the UK are too twisty and too crowded for that.

I'd guess, though, that the actual real-time of a spell at maximun throttle isn't as long as we percieve it to be when were doing it. I wonder - could it really be that the faster we travel, the slower we experience time passing? Perhaps I should ask a relative.
:razz:

I rode at top speed for a few minutes on a long straight in the middle of nowhere, Texas.

I was at redline in 5th (7k) at 115 or 120mph indicated. I probably did 2-3 miles at that speed.

I rev mine to 10,000, it's almost stock :-D

A stock bike should last for ever at 7400rpm if it's in 5th. In 1st it might run hot after a few hours :wink:

ThruxLove

I have about 1030 mi on my thrux, so I let it go to 8000rpm then shut it down. Where is the rev-limiter set on this bike?

RedBird

I believe the stock rev limiters are set at: 7400 rpm for the 790cc motors and 8000 rpm for the 865cc motors.

I have run mine all day long at 5500 rpm in 5th--that's minus the stops every 100 or so miles for me--I'm much older than bonnie. :-D

It really depends on how long you want the bike's engine to last. Apparently many here don't care.

It has a rev limiter to keep it from blowing up now. Unfortunately Triumph expects us to use our brains to keep it from blowing up later.

Have fun, but don't complain when you are having the motor overhauled.

Bottom line: the longer you run it at or near the red line the quicker you wear it out, risk heat damage, stress metals, force the oil to work beyond its capibilities, and test the design characteristics of the engine, an air cooled engine, I might add. An awful lot of people here either don't believe that or don't care.

Its your bike. Do as you wish.

Monte,thats an interesting take on things. Following that logic,I expect to NEVER get a scolding for switching to the 19t sprocket. :-D

Guess not. I really don't care if the guys here want to try to ride their Bonnies as if they are 1000cc sport bikes, but I do think they need to at least understand that these little air cooled engines are not likely to take kindly to having their necks rung out on a regular basis.

When I was young and invincible I thought my bikes were too. I was mistaken. When I raced scrambles and flat track I knew we were abusing our bikes and expected early problems and failures. And while things are generally better: eg oils, metals, etc. they are not that much better. Triumph knows that they are not building a sport bike engine for these bikes, hence the relatively low rev limiter settings.

The closer you play with fire the easier it is to get burned. Just don't be surprised if you do.

They won't listen anyway, but it is fun to pull their chains now and then with a little common sense, a comodity too often in short supply.

Monte :-D
