Hey guys,
Just got my set of Z6's and was wondering about the break in process.
How many miles until they are broken in?
What if I don't lean far enough?
What am I breaking in?
What if I just scuff the tires with sandpaper?
Thanks,
Jack

The easiest and surest way to scrub in your new tires is to navigate a 25 foot diameter circle... about 10 passes to the left and 10 passes to the right will scrub the nearly all the way to the edge and leave less than a 1/8 chicken strip... not to mention your building heat near the edge as well as the center of the tire... so by the time you get to the bendy bits you'll be ready to go full lean with full confidence that the grip will be there for you...
Everyone has marked a 25ft diameter circle out in front of their home right???

You know, I've been riding for about 10 years and I still can't do a good slow speed circle, or a tight u-turn like that.
I've always heard go easy the first 100 miles. Wouldn't hurt if you have a cul de sac like BSL Larry. :beer:
Take it easy for the first few miles, slowly increasing your lean angle every few turns until you have them scuffed edge to edge. On a good twisty road you can have them well scuffed in within 25-30 miles. Once you have roughed them up edge to edge and put them through a heat cycle they are pretty much ready to go.
I scuffed in a set of brand new Diablo's at Deal's Gap with just one pass down the Dragon..........it does not take long to do.
dude if you do the cul d sac method be SMOOOTH with the throttle. yes i have wiped a bike out on new tires doing my scuff in method. (although it tends to involve a little smoke)
guess i'm just reminiscing my squidly days :)

Have you taken an MSF basic riders course???
MSF The trick to do a smooth circle is steady throttle... modulate the clutch to feed power to the wheel... crank in nearly full lock steering... tap the rear brake to adjust the lean...
concentrate...
According to Metzeler...
How long is the run in period for motorcycle tyres?
In order for the new tyres to provide optimum performance, all new tyres must be ridden very cautiously for the first 100-200 kms. Immediately after new tyres are mounted, sudden acceleration, heavy breaking, and hard cornering must be avoided until the 100-200 kms run in period is completed.

Metzeler FAQ linky
You read what Metzeler says in a FAQ but then they will turn around and sell new tires at the race tracks which are mounted... raced and discarded without the 100 to 200 kms run in period... it seems all that is really required is proper heat and a good scuff in...
I think track tires are different, at least the racing ones.. They're only designed for one heat-cycle, whereas most street tires are designed to work properly _after_ one heat-cycle... ?

According to AMA rules track tires are the same as DOT approve tires which technically are the same tires we buy off the shelf with the exception of the more current tire manufacture date... in other words they are only fresher...
I don't have a cul de sac. So I use a concrete parking lot but the same method.

I guess a 25' circle should be pretty easy compared to the 18' circle I practiced on at motor school. :D
I suppose you figured it out by now as this post is getting old. So what did you end up doing? I ride semi easy for about 30 miles and push it a little more each mile. It scuffs in rather nicely. If it slips a little, back off for a little bit.
I do the same as Lewis.....once I hit 100 miles I figure they're scrubbed.
Take it easy a first(no serious lean angles) and gradually work it up. It's kind of a piece of mind thing I guess.
