I'm scheduled to take delivery of a brand new 04 955i within the next week or so.

On the gas tank is a decal advising break-in speeds and rpm's.
But they seem impossible--- or at least a lot more constraint than I'm probably capable of. IIRC for like the first 100 miles no more than 1500 rpms--- which would give a ridiculously slow top speed woudn't it?

How have you guys broken in your new daytonas? How much constraint is really prudent?

thanks,

Hi

I'm busy with a new 05 model at the moment... now up to 550 miles and 6000 rpm.

The first 100 miles is a pain... but not impossible. 3500 is about 55 mph.

The salesman who handed my bike over told me not to worry too much about the limit under acceleration... use up to 4500 ish, but settle at 3500 at the cruise. To be honest, 100 miles at 55mph isn't too painful - find a twisty road and 55 mph is fun! To be honest I stuck to it pretty religiously for 60 miles, then added 500 rpm every 20 miles to build it up to 5000 by 100. There's nothing magical about the number on the speedo... again now it's done 550 I'm building the revs up slowly towards the 7000 I can use continuously at 600. Surely makes more sense to me as an engineer than suddenly using another 1000 rpm because I've passed some random point on the odometer.

An engine tuner and specialist once told me how to run in a new engine... his advice matched the above, but moreso... don't worry about revs through the gears, it's heat that kills engines... don't get it too hot.

It's a good idea not to drone along at 55 on a highway... varying the revs is much better.

If you do a search on running in motors, you'll find some other interesting concepts like give it three or four high rev cycles then thrash it... personally I'd rather stick reasonably close to the manufacturers recommendations and add a little common sense.

Dont be to hard on her , keep under 8000 rpm and dont keep the revs too constant , change gears alot .Do this for the 1st 1000 miles and u will be fine .Mine just keeps getting stronger and stronger....

I just went off the ticket, if your going to keep the bike you may as well do what they say, afterall triumph make them they know how to run em in!

yeah 100 miles goes by fast....just keep it respectful and don't keep the revs at a constant.....its good to find a nice country road and just enjoy an afternoon or two and get the mileage up to 500 or 600 miles...thats easy to do in a leisurely weekend.

I've got 2 words for ya.."Shake and Bake"...oh yeah that blew you mind didn't it????.

I stick religiously to the first section of the run-in and then ride it normally after the first service.

I've owned all of my bikes long term and have never ended up with a smoke blower or a rattler.

Also, always amazed at questions such as this, especially when you look at how many miles are on the average bike for sale second hand. These bikes are barely run in when they go up for sale. If you intend to have the bike long term, treat it accordingly IMO.

I hope you enjoy your bike. I'm very fortunate where I live as it's ideal to run a bike in. Mountain roads equals many gear changes, rev range is always changing and it's fairly quiet so I can set my own pace. I also have a Freeway section if I choose to use it.

Great bike, be safe.

Linz :-D

Yeah, Mike, the first 100 miles is a PITA, but it does seem that Triumph still prefers everything to wear fit during a good old fashioned break-in.

Thank-you everyone for your comments and advice.

I may have (faulty memory) errored in thinking the label said 1500 rpm's during the first hundred miles---

hopefully it is the 3500 r's that was mentioned giving a top speed of approx 55 mph--- which would keep me from getting run over :-D

and I'll find a nice two lane road (early, early morning jog up rt 32) to clock my first hundred miles.
