I was about to post this vid! It's awesome isn't it! There's a go-kart track near me, but I doubt they'd let me on with my bike because of various nanny state laws designed to protect me from myself. I can see how this kind of thing is more common in Taiwan where they have a bit more freedom.

Many of the kart tracks around here are no go on the ninjette and honestly it looks pretty tight for one, but that is awesome.

The kart track near me doesn't allow anything bigger than 100cc unless it's a supermoto.

Ironic how freedom really means the freedom to take everyone else's freedom away. That's my view on nanny state laws designed to protect you from you in a nutshell.

My local go-kart tracks won't let me take a bike out there of any kind :/ luckily they're still fun as hell in go-karts

hmm, would they accept a non street legal 125cc 2stroke dirt bike w/street tires and bigger brakes? The conversion is easy enough to do and would be worth it down the line for the cheap track time.

Inspirational....

I'm sure many have seen this video, but wanted to post it just in case some haven't..

Link to original page on YouTube.

Like many of us have heard, our little Ninjettes are only beginner's bikes, aren't real bikes, etc.. My first bike was a Ninja 600 a LONG time ago, and I was decent on it.. However, my primary "extreme" riding was done on a drag strip.. Straight line stuff, no knee dragging (Not intentional, anyway!), so on and so forth.. Since getting my 250R, I'm working on my skills, always looking to improve, get that extra inch of lean angle each time around a corner.. Watching this video makes me realize how much more fun this bike can be if we put in the time, effort, and focus.. Let those with the larger bikes talk all they want, and then leave them in the dust when they slow to a crawl around a tighter corner..

That's a pretty exciting vid and very interesting because it's somewhere between track and gymkhana. I'm a total noob at gym and never been on a track but the vid makes me wonder at what speed, turn radius, straightaway length gym technique works better than track. I mean...just out of curiousity I gotta wonder if an "average" gym rider could've completed that course as fast as the "average" track guy. Go kart track riding...do you have that over in jersey?

I live about 15 minutes from New Jersey Motorsports Park, which wasn't around when I had my 600 all those years ago.. I do plan on going to NJMP this season though..

I raced karts when I was younger, and even spent some time in an open-wheeled car.. Admittedly, I've never slid my knee intentionally on a bike, because I've lacked the skill to do so.. I intend to change that though.. The thought process of how to attack corners and such on a bike versus a kart are relatively similar.. In a kart, you must shift your weight and look a few corners ahead if you're going to not only be fast, but be safe.. The major difference is obvious, two wheels versus four.. Everything becomes exaggerated on a bike because your going beyond a simple weight shift and adding lean into the mix.. I know I have a lot to learn, and watching/studying videos like this only makes me want to learn more..

I don't want to just RIDE my bike.. I want to EXPERIENCE it as fully as possible..

Spent many a night at Raceway park....I still have the hearing damage....jets vs funny...never saw anything so exciting in my life. I dont have the balls or time to go to NJMS so I got into motogym. Seems most of you jersey guys have track experience. Rode with TriStateSportbike crews a few times...I was so outclassed I bought a v Strom. If you're deep into technique...watch a gymkhana vid, braking techniques

I have ridden my 250 at a cart track. It's wicked fun!!!! It's closer to track riding from the skills perspective than gym imho. This is a great way to get your feet wet before biting off a full sized racing circuit. Riding these tiny tracks will teach you 2 vital things; how to steer quickly to set your line and how fast you can move your bp from side to side. (hint hint @Sirref) It was when I rode the cart track I learned; you can flick the bike hard and fast enough to thump your knee on the tarmac. It was that day I said; "I stopped GUESSING what my bike was going to do and TOLD my bike what it was going to do."

I have posted this before; "if you have a cart track that will allow 250's out there, DEW IT!!!!" It's much, much cheaper and shouldn't have the more strict gear and tech requirements, but don't skimp on the gear. A broken bone hurts just the same at 25mph as it does at 125mph. ijs....

And don't make the same mistake that I did, GET VIDEO!

There's a kart track 10 minutes down the road from me and it's a nice facility but extremely underused. They had a few supermoto track days a couple summers ago but that's it. They wouldn't let me take my 500 out on the track and I don't think they'd let 250s out there either. I guess it's under new ownership or something because guys used to take their 600s out on it for kicks n giggles.

I've tried, the ones near me will not. Though there is that mini-moto thing in VA that @Finesse does which is about as close as I've seen or heard of in the general area

Visited the most "local" kart track I know of that allows mini bikes (in the car passing through unfortunately) last week. Seems like a pretty nice facility. I am itching badly to get out there.

What has (lowish) speed got to do with "difficult lean angles / speed" ?

And btw the track is here :
http://www.kartingasia.com/kart_trac...cuit-t259.html

And the rider never was going as slow as 20 km/hr, more like 40-60 km/hr

It would be because the centrifugal force is related to the square of velocity. Simplified the faster your moving around the arc of a turn, the greater the force pushing you outward - to combat this, physically you lean the bike at an angle and use this force to drive the contact patch into the surface to create additional friction force for the tire to grip.

I didn't write What has speed got to do with "difficult lean angles / speed"

I wrote What has ("lowish") speed got to do with "difficult lean angles / speed" ?

You described what happens with any turn.

From what I've read re: lean angles, the lateral forces are the same for a 45 degree turn, whether it's 22 mph for a 40 foot radius, or 50 mph for a 200 foot radius, etc.

Somehow, the ("experienced") vlogger seems to think that a 30-40 mph "max-performance" turn is "extremely difficult", while he thinks "to get your knee down on a high speed bend is fairly easy"
what experience do you have to back it up?

You are correct, I did describe what happens with any turn......specifically that increased velocity has the effect on increasing the force pushing you away from the center of the arc/turn. What you read/believe is incorrect, the lateral (although lateral is not the best worn since we are talking angular movement ) is not the same. That is why I posted the FBD with the formula and the relationship can be clearly seen.
