That sounds like my experience when trying to launch BRPs

BRS actually have one of the smoothest transitions to losing grip imo.
I think these are just too heavy, kind of like when I try to slide the giant torque board urethane wheels.
Agreed it’s a smooth transition on BRPs when in a corner just not in a straight. Rubber pneumatics lose grip much more smoothly in my experience. I haven’t experienced the skippiness when sliding so likely don’t know what that’s like.
It’s interesting because Dylan seems to be able to slide the wheels no problem but guess we haven’t really seen anyone else try it yet. So your experience is definitely interesting. At Esk8con we didn’t really get to push the board that hard.

Our track is super grippy, so that could be a big factor. Also

Are you referring to the Mach1 here?
The board has a pretty huge setup range. Even for me one wrong bushing is enough to ruin my experience. The double cones at the front work with the R6 trucks to allow for a lot of lean and initial turn in but still super stable at 45mph.
Of course a lot of bushing tuning is personal preference but thats what I found to give the least tradeoff between turning and stability.
The SR125s are designed for street riding and commuting as well as going fast and feeling super stable. People who prefer a more traditional longboard feeling usually prefer smaller lighter wheels like Mad 105 which completely change the board again. It does also take time to get used to the SR125s. I didn’t like them for the first hour and then when I got used to them they became my favourite wheel.
For track riding competitively you’d want BRPs or 6in pneumatic and a front binding but even then it’s not really built to compete with 3 link trucks. The R6 have a lot of kickback when taking corners fast which makes them feel really nice on the road but understeery on a track.
And if you want to slide it, Mad 105 or onsra 115mm are good choices.

Yeah the rider was heavier, we tried messing with bushing tightness. Hopefully he brings it out more, tried it like 4 times, wasn’t bad. I think I was just expecting something else. Should have the riders put a zip tie and heat shrink on antenna imo, the straighter it is the better and won’t get chomped up, we do it for fpv racing drones
The raith actually has a window of only fiberless where the antenna is to prevent carbon interference.

The mach1 has a window too on the enclosure. Antenna doesn’t stick out that’s something the owner did to get better BT reception as the makerx BT antenna is quite weak. The 2024 model has a kevlar deck so the entire top deck is a big window to address that.
Hopefully you get to try Jeff Peralta’s board with softer setup and RTS at some stage and do some street riding. I think he’s planning to attend as many ERL and other race events as he can. We’re also going to get him the track package Dylan had for esk8con with BRP wheels and high castor/rake front hangar.

Dude, you’re gonna make me see a therapist in the future 
Therapist: So how did you develop your eating disorder?
Me: Whenever I go to the Chicago I2S, no matter which board I bring, I get chastized for my bushing configuration 
j/k
My experience with the R6 trucks: they’re an absolute knockout in terms of pure, unadulterated fun. I could tell this the first time I jumped on an M1. That said, they feel pretty different at first; almost hyperactive to road imperfections, but not unstable. It was a bit disconcerting, and it took about 40 miles before they started making better sense in my brain (note that they’re not actually hyperactive, that was just a perception at the beginning).
There was also the mental barrier of riding the stock bushing config (double cone in the front) which seemed odd, but I stuck with it to get a baseline before I started mucking with things. Turns out after getting used to how the trucks felt, double cones in the front is pretty sweet for street (expected) but also stable at speed (unexpected). Curious to see what it would do, I replaced the top cone with a tall barrel (same duro) just before I2S and rode out. Even though it wasn’t cranked down, on the ride there it definitely felt too tight, and I ended up swapping back to the cone shortly after getting to the track.
Took a couple laps, let some other folks take some laps, and we ended up backing the kingpin nut out as far it probably could go. At that point I could hit the apexes on all the turns except the hairpin, but that was mostly me taking the turn at the wrong point. Morgan ended up tossing some lines down for me to follow to address that, and I managed to hit the apex on the hairpin reliably, but I get what @Tony_Stark was saying about the understeer – coming out of the hairpin I would drift out a bit early despite hammering on the side of the board to hold on, almost like it was trying to rebound me out of the corner. That works awesome when taking turns on the street or threading vehicles, but on the track I could see why it might not be someone’s preference. For comparison, hitting that hairpin on a 3-link board was dead simple and I could shoot out of it like a rocket. That said, the lean I was getting on the R6s still felt great and the SR125s were planted as hell despite my weight (take that eating disorder!).
I might keep stepping down in durometer on the cone since I’m as loose as this config allows and I’m curious as to how it’ll behave on the track going even further. Also might go even further down in duro but use barrels instead to see what that feels like. My concern is that the lower in duro I get, the less effective the bushings will be if they end up just getting stuck in a compressed state. But whatever, it’s fun to experiment.
Anyway, just my thoughts as someone who prioritizes street carving with sprinkles of stupidly fast when there’s a nice section of road over being a pure racing junkie. Though I do have a 3-link setup in the works…

Legendary feedback, thanks for putting in the time to give such detailed thoughts on the way the board feels!
It’s awesome to hear that you’re pushing the board on track as well instead of just dusting #00 off every once in a while for a chill coffee run. Mad respect 
I think the R6 trucks are a little different compared to most others when it comes to bushing setup and can be a bit counter-intuitive as to what ends up working well in them. Where you ride also dictates a lot. I went down a couple duro’s in Vegas and when I got back home in Melbourne I went straight back to the harder bushings because despite the roads being much smoother here they are less flat and throw the board around a lot.
That “hyperactive to road imperfections” feeling is actually the SR125 wheels. The square flexy lips and offset core is the secret to how they turn well but feel planted AF, but the drawback is that the sharp lip rides up imperfections in the road so it will feel hyperactive on uneven surfaces. We’re doing some testing with more rounded off corners at the moment to see if we can improve that without losing stability and grip. The V2 wheels had very rounded corners and lost that on-rails urethane feeling but I would like to improve the transition from grip to slip a bit so we’ll see how the rounded edges go very soon.

Oh I didn’t stop to think it might be the wheels. That plus the “smooth but less flat” roads interacting with the bushing combo description matches that feeling I hadn’t experienced before. It makes sense now. Suggestion you can take or leave: start tossing all these concepts into an FAQ or (if you want to get all corporate-y about it) a knowledge base on Radium’s site. It’d probably help with not only getting people to dial in their shiny new M1s without scouring forum threads, but also in setting expectations for people who just picked one up. This tech is new to most people so there’s a tiny bit of a learning curve.
Hell yeah, it’s too fun not to ride this thing almost daily. Also the I2S Chicago group is super chill; I show up when I can just to have a place to push a board more than I can riding around on poorly maintained streets in a city full of dumb drivers. Definitely helps you learn your board in a deeper way in a safe environment and I always feel more confident riding in general after a session there. I’ve seen everything on that track from the usual folks running Stooge setups to OneWheels to EUCs to tourists on Segways and every mainstream board ever, including a dude last fall running laps on a Propel mtb with that coil-loaded suspension (looked like a bus trying to turn in a hallway on some of those curves). Props to @Zachsnotboard and Morgan for putting in the effort to set up the track, constantly sweeping the debris, and dealing with aggressive Canada Geese that periodically like to establish dominance.
Last Saturday the cops swung around us in a helicopter a couple times, probably because they were jealous (videos stolen from other people).
If anyone’s ever in the area, you should definitely swing by (the warm weather location is in an absolutely beautiful spot on the lake); give me a heads up and I’ll bring #00 for you to do some laps.

Dude, so good to have you there always!
I enjoyed riding the radium, but for sure think some other bushing setups would be very fun to try. Thanks for bringing it to i2s and subjecting your boards to the bushing bashing:rofl:
My personal opinion would be I’d want to try it on dual barrel and a softer duo.

First thing I did was remove the black paint on the cores.
Who rattlecanned these? @glyphiks or @Tony_Stark ? Lmao

You mean spray painted 
yea they didn’t paint them it was done at the factory same is happening to mine all the 125 wheels I was told have that happening to them due to them being first batch or something 
That’s what rattlecan means haha
