I just thought about something.... Everyone said to stop breaking and use more entry speed... I havent been trail braking anymore than i would have on my r6 and that bike weighs more... i never used my tire at all, most of the time when i changed the tire it still looked brand new each time. How does a bike that is going slower and weighs less tear up a tire from the same amount of braking??

Also more entry speed... My BP is pretty good, i know it could be tweaked some but its better than a lot of riders.. Im running out of rear and damn near front, wouldn't higher entry speed result in even more lean angle??

Just something i was thinking about when i was driving to work at 3AM this morning, so bare with me if its completely wrong haha

I honestly dont know why your front went away like it did. Like you, I usually go through 2 rears to 1 front and the fronts still have plenty of tread left at that point. Is this the first time it ate the front like that?

Dsheumaker · June 5th, 2015, 09:05 AM

This is my first set of tires on the bike, but the front did not wear like that at NCBike or my 5ish weekends on the dragon.

Near 200lbs of rider with some skills on a stock setup ninja, turning like he is and taking those lines is gunna eat fronts.

Basically, your quick turning in places that you don't really need to vs. adjusting the line and attack angle of the turn in point. For example, the slow right hander; your turn in point is very deep into the corner and steep. While the turn in point looks good, the angle of approach to the point sets up a quick turn with quite a bit of lean (squared off). Save that line for when you need to defend an inside pass vs. every lap.

A smoother and safer line can be carved through there by approaching the turn in point a bit wider. If you don't try to square off the corner so much, you won't have to steer as hard. The end result will be carrying more of the speed into the corner. Which is what most of the riders are saying here.

Changes in your line/turning riding can/will buy you some time, but git ya some front springs from rt or sonic, balance the rear and this problem should magically go away.

You can go plenty fast on the stock bits, but that don't mean it's ALL good.

You can be confident that the track surface accounts for a certain amount of the excessive wear as well. JenningsGP eats my tires as well vs. getting great wear on the other tracks I ride. ijs

Dsheumaker · June 5th, 2015, 09:33 AM

Guess I have to spend more money...

Dsheumaker · June 5th, 2015, 09:34 AM

I'm so used to diving deep and flicking, not sure if I can change that....

csmith12 · June 5th, 2015, 09:37 AM

If you want to go faster you can and you will.

Dsheumaker · June 5th, 2015, 09:38 AM

I'm gonna blame it on the dragon... Trying to stay away from the yello line..

Dsheumaker · June 5th, 2015, 09:39 AM

So Springs, tires, and new lines... I've got some work to do haha

csmith12 · June 5th, 2015, 10:48 AM

Like I said yo, I think we are sailing the same ship. When moving from my r6 to my 250 I have to make a mindful shift in my riding. Yami's have such a stable front ya know... an r6 is happy as long as the front is stable, the rear can do just about anything within reason and it can be ridden out. You simply don't have this luxury on the 250. At pace, the front is wishy washing, the fame is flexy and it has no power. Trying to go deep and flick it and make up the speed difference with the throttle just doesn't work well in most corners. Ya know, go fast in the fast parts

. Salvage what speed you can in the slow parts.

The evidence is in the vid, how you take turn 1 vs some of the others.

Dsheumaker · June 5th, 2015, 11:35 AM

I haven't even watched it haha... Thanks man

are you sure? you may be surprised how close those weights really are.

and as others have said, you don't need to square off corners with a 250, in fact you lose time doing that compared to a 600/1000. the bike has no power, where you get your speed and time is carrying insane entry and corner speeds.

375ish (250) vs 417ish (r6), that aint much in the grand scheme of things.

Dsheumaker · June 5th, 2015, 12:01 PM

Just watched the video... Damn I'm slow on this thing! Haha

The power to weight is the kicker.
