Hey all
New to the track still just started this year.
I was wondering what’s the best thing to do with my bike on outside berms corners. I have a 2020 crf250R. Before this weekend I was pretty well using 3rd gear around the whole track. And when I needed more go out of a corner I would slip the clutch to get it reved up. Now reading and talking to friends of mine no one does this with their 250F’s.
So the track is about average 2.40 a lap. Is a loamy type track not hard pack at all. The outside berms are for the most part packed with some fluff at the exit at times.
My fastest lap staying in 3rd for the most part other then taking the inside ruts. has been a 2.44.8
Yesterday I went out And instead of slipping the clutch in 3rd to get it reved higher I tried shifting into 2nd on a lot of the outside berms. (The bigger sweeping ones I stayed in 3rd still) and I noticed I could rev it way out more and got more drive. Then shift into 3rd just after the exit. Well it must have worked because I clocked a 2.38.
Question is, I’m assuming it’s better to do your breaking bang it into 2nd just before you get to the berm, hit the outside berm let it rev in the power then shift into 3rd instead of slightly lugging it in 3rd and having to slip the clutch to get into the power on the exit ?
To me it just always felt slower because it’s reving so high but I guess it’s faster.
Thanks !

Get a LitPro, do half the moto revving, half lugging. You'll see where it works and where it does not.
What’s the best thing to do do my breaking then bang it into 2nd then corner ? Or bang it down to 2nd then brake ?
Thanks all

When I shot competitive archery, this or that would sometimes 'feel" better but my scores didn't reflect it. You don't win with "comfort", you win with the fastest time or the best score or whatever. I found out, for instance, that some tension in my bow arm helped me hold steadier and shoot better scores (and we're talking like 1-3 points out 300 possible. One shot difference out of 60 shots).
I've got a LitPro and it's great. Shows me where I could go faster around the track w/out even going faster (better lines), where I could go faster by going faster (I tend to maintain a constant speed on long straights), and where I could go faster by going slower (braking earlier for turns so to go thru smoother and faster).
On your actual Q, on my 250F.... it just depends. Do I need power in a soft corner? Shift down. Harder packed corner? Leave it up. Etc. You gotta play with it and you gotta use the stop watch.... maybe even from a point going into the corner to a point coming out (which the LitPro does).
You'll need an i-something. I hate Apple stuff, but I do have an iPad Air that I use with my DJI drone, so I use that. To do other fun stuff like match your heart rate with it, you'll need an appropriate monitor. I don't use that so I don't know. If you wanna match video to the track info, you need a GoPro. But all in all, the basic XGPS 160 and an iPad/iPhone/iFuckingWhatever will give you so much information that it'll probably over-load you. I used to do data analysis for a living so I eat this stuff up.
There is a learning curve, most of it related to the way Apple thinks which is just NOT the way I think. I use Apple stuff and it's like playing Myst again. I don't know what I'm supposed to do, what it'll even do, and I don't know how to get there. I want a damn drop-down menu so I can see what's there.
Go here and see how it all works:

How the heck does this thing know your track. Does it map it out going around it etc? Thanks
Here's a sample of my home track.... I used this to link the GoPro video with the LitPro software. A word of advice... if you do a multi-session thing be sure your LitPro and GoPro have the same time. Otherwise, you'll never remember if you rode the Husky or the KX250F on that session and you'll never be able to link the footage. Also, be careful to not enter the track over there and exit over here... if you have to do that, then set your enter point as the "starting" line and your exit as the "finish" line. If you don't, you'll lose two laps of data- one when you enter and one when you exit.
I put the LitPro on my son and compared his data to mine and from that I found out:
1) He's faster on the straights. I get a speed and stay there. He accelerates until he brakes. I wasn't going all-out in this video... just working on smooth lines in corners and getting exercise. He goes all-out, every time.
2) He brakes earlier but softer than I do. He lets off on the brakes earlier and gets on the gas earlier while I'm still braking hard into the corner. You can select "decel" as an option and see this. Because of this, his actual corner speed is 2-6 mph faster than me. He makes massive gains here.
3) I'm actually faster on the exit of the corner, but he goes in much faster and hits a higher max speed on the straights.
4) If you use an outside line, you've got to go a LOT faster to beat the inside line. Using the LitPro on a "real" track showed me w/out a doubt that this line or that line was faster.
5) sometimes a slower line is faster. Inside vs outside again. What this tells me is, without even increasing my actual speed, if I pick the better line, I'll have shorter lap times.
So... what I'm working on is slower braking earlier to get more entrance speed, smoother corners, and hitting a faster speed somewhere on the straight. Unfortunately, I'm 58 and on the downslope and he's 17 and on the upslope, so it's gonna be a tough battle to beat the kid.

I think I normally would brake first then down shift as that wouldn’t upset the bike as much I would think ?
Thanks
You'll just have to play with it yourself and experience will guide you later on.
There's literally somebody a few posts up using Eli Tomac (and his clutch technique) as a "bad example" of cornering technique, posted in complete earnestness, as if Eli isn't one of the best guys at negotiating turn in the history of the sport.
Post a reply to: Let it rev higher or lug and slip the clutch out of corners ?
