All Z125 Track Racers are encouraged to post on this thread.

The Z125 should qualify for the MiniMoto and MiniGP Racing Series as well as other local and regional race series (to compete alongside Groms & others).

Kawasaki may well create a Single-Marque Racing Cup Series like Honda did with it's HRC Race Cup Series for the Grom.

Hopefully the Forum Admins will move this thread into a newly-created Z125 Pit Area Forum Section and add Track Discussions, Track Days/Racing Courses & Events and Pole Position and Grid sub groups within that section. Hint, Hint!

I am working on finding venues for racing and/or just track day fun around here. I have a lead on a pretty good looking track in delmar IA that seems promising. Also, I plan on converting the little bike into a ninja Z 125R as I am gonna call it.
I'm hoping to check out a practice day with the NJMiniGP org that runs at New Jersey Motorsports Park. As of now, the Z125 can run in the F1 class.
I believe MiniGP has a Grom class, but as far as I know, it is Grom only, the Z can't run in it.

I'm hoping WERA racing, which has a Grom spec class (which the Z can't run in because it's a Honda spec only) will eventually add a Z spec class, or a combined class of some sort. Although, I think there are probably other mini classes the Z would fit into, haven't looked into that.
Track update: I received approval yesterday for two kart tracks and they are both interested in getting a mini-bike series together. TNT Kartway in West Quincy MO, and 61 Kaart way in Delmar IA. I can see a Midwest series starting to take shape!

You might also contact Kansas City Karting Association in Liberty MO. They have allowed Grom/mini bikes to work into their established racing weekends and are a good group. The turnout has been very low but perhaps you can rally some Z125 aspiring racers to join you.

I spent a few hours on Saturday at the TNT kartways track doing several sessions. I will be putting together a video of it all as well. Had a seriously fun time out there and many thanks go to the people running the track. For $25 a day at the track including a pit pass, its hard to beat that much fun for that price!
Can't wait to see this happen in the eastern part of the world since they have had the time to buy these, meanwhile we haven't had as long, but the culture here is still strong. Good chance some of these are already being prepared for the challenge or at least planning being done for it.

How was the grip? The number of changes in track surface from years of repair look like it could cause issues when on the edge of adhesion.
cfaddict, looks like fun!! Were you running stock tires? I'm doing my first kart track day next month and will run the stock tires. If I like it and keep doing it, then I'll upgrade to better rubber. Just wondering how the grip with stock tires is, if you used them.

The grip level was surprisingly good and yes it was the stock tires...although I didn't push all too hard. I was dragging the pegs here and there though. There were a couple older sections that I really took it easy on to be safe though.

Yes, stock tires....They're pretty decent imo. I did monitor the pressures and they did climb a bit...I tried to keep them around 26-28 psi and never really had any issues with grip. It was a pretty warm day..ambient around 88 degrees and full Sun. The tires were good enough to no longer have chicken strips and I was grinding the pegs somewhat often .......translation...I should get off the bike further and lean it less and I can go faster!!

We have a local go-kart track that hosts AMA SuperMoto events as well as mini bike endurance races and Grom races. We were able to get the track to ourselves and have some fun battling these bikes out.

TST...no video link?

I am gonna be hitting up 61 kartways here soon...that track looks like its gonna be a serious workout haha!
Man... thanks for posting this! Really shows how the bike works out there on the track. Have you done any mods to yours? I couldn't really tell, other than the GoPro mounts.
no mods other than the go pro mount and removing the mirrors for the track. Today though I was playing on an un used round-about and definitely found the limits of the stock tires. got the rear loose a few times when I was cranked over. plenty of tire though to get knee's on the ground consistently. it was only when I started really pushing for speed and making adjustments while leaned that I started slipping...my rear shock needs replaced though so that may be part of the issue.

The Z125 stock tires are plenty good enough to track. I just went over the weekend and it's definitely track worthy.
The stock pegs even though are pretty high stock, they definitely hit the ground. You can get enough lean to put down some quick times though. I ended up running my tire pressures somewhere around 20psi hot.

I am still trying to figure out how I want to mount my gopro, I don't want to sticky tape my bike, and I definitely don't want to sticky tape a mount on my helmet either. I have some crappy iphone footage on my cell phone mount, but it's not even worth posting.

I did a back to back comparison with my grom at the track as well. I cant tell you how much more well put together the Z125 is. Even though its not as torquey as the Grom, the gearing is so much better for the track it just feels right. The tires that come with the Grom is not trackable. I'm sure with enough parts thrown at the Grom it will finally be on par with the Z125.
