Proper (LEGAL) break in

RidinFast · 12-31-2004, 8:49 PM

OK, This may sound stupid, but hear me out.

Today was the first semi NICE day out and I took my new CBR1000RR out for it's FIRST ride.

Proper Break in (depending on who you talk to and who you believe) is to vary the RPMs up to 7500 the first xxx miles then up to 10000 for xxx mioes, then finally up to redline.

WELL... I found out first hand today that at 7500 in FIRST GEAR, I am WELL over the posted speed limit...

How am I going to Legally run it to redline? (I know.... take it to a track)

It's just AMAZING how powerful, yet smooth and controlled this bike is. Brakes are AMAZING, and I can steer it by simply pressing on the tank with my knees. What a WONDERFUL ride!

I envy you - nice ride! Many threads have been started regarding break-in. I probably babied mine, according to most of the accounts I've read here. Seems like modern engines can take quite a bit more that the manufacturers recommend.

I think you should ride it fairly hard in the beginning, but not keep any sustained high rpm's going. It is a VERY debatable subject, and as far as I'm concerned, the jury is still out.

edit: Yeah, I know, that didn't help much...

Ride it like you stole it.....I have 350 miles on mine and its on like donkey kong!

RidinFast · 12-31-2004, 9:26 PM

I can just see it now. But Officer, I was just breaking it in, and "varying" my RPMs... I swear I was speeding on purpose... I was just following break in guidelines...

Bike Break-In Procedure

7500rpms in 1st gear shouldn't exceed the speed limit. Especially on the highway. You should be able to hit 7500rpms in higher gears, even.

on regular roads its way to easy to go over the speed limit at those rpm. When I ride around town on my 929 (stock gearing) I sometimes don't even shift to second because I'd like to keep the rpm above 4000 and 4000 in second gear is around 32mph (5000 if I stay in first). around here most backroads are 30mph and main roads are usually 35-40.

Looks like I wont legally need anything other than 1st and 2nd...

Ahhh the joys of to much power

Don't get overstressed, while the break-in is desirable, the bike will be fine either way. Moderation in throttle and adherance to 'procedure'. Enjoy it.

82mph topped in first, I think that should get better as the engine loosens up a little. I top out at 77 in first (only did it on the highway and yes technically illegal, thats the flow of traffic anyway so yes I was screaming but not really going all that fast)

I'll be the first to admit I know little about Motorcycle mechanics, however, I DON"T think your speed / gear will change at all when the engine loosens up.

You're gearing in limited to RPM and gear size. Unless you change the gears, sprockets, or raise the RPMS, it shouldn't matter if you have 10, 100, or 1000 rwhp, your speed / gear will remain constant.

If I'm wrong, please feel free to "set me straight" but I KNOW thats the way it is in cars and transmissions. Engine RPM and Phyical speep will NOT change with more or less engine power. (It MAY take you LONGER to get to that speed, but the MAX speed will remain a constant unless you change gear ratios (or tire size).

I'm by no means an expert but once the engine loosens up you gain a little more power so it takes a few less rpm to arrive at the same speed you were at before in the same gear.

PS94 · 01-01-2005, 11:32 PM

No. You will not get any more speed at a certian RPM without a change in gearing, ridin fast is correct...

The crank shaft is connected to the clutch. The clutch in connected to the transmission, the transmission is connected to the front gear, chain, rear gear, wheel and tire. There is no way the RPM will change at a certain speed in a certain gear by having more power. It'll just accelerate there sooner.

Do the best best break in you can. A really important part of the break in
is engine breaking. Get the bike wound up pretty good then just let go of the throttle. Don't downshift, let the rpms get down to idle if possible. And then repeat that a much as you can without causing traffic accidents.

Most any gear will do but you have to get the rpms up pretty high. My $.02
