Yuuki Sato (nicknamed Ma-chan) of Hello! Project group Juice=Juice sparked discussion on 5ch’s Hello! Project board after posting, with a radio-show hashtag, that she owns “a motorcycle that isn’t a moped.” The thread exploded with guesses about the model — Hayabusa, ZX-12R, Harley-Davidson — while posters recalled how she’d reportedly failed the written driving test multiple times before finally passing, and brought up the fact that fellow idol Miki Fujimoto has been in two traffic collisions in the past. Some pointed out that under Japan’s revised moped classification, bikes up to 125cc can now be ridden without a full motorcycle license, which added to the confusion. In the end, her actual bike model was never confirmed.

Wait, she's still around?

Guys who only ever say 'wait, still around?' — are THEY still around?

I feel like I saw Juice=Juice when they came through Matsubara City.

Isn't she the type to wipe out right after filming the 'bike delivery day' vlog?
10AnonymousNov 2, 2026 12:41
If she ends up hitting someone it'll make the news and reflect badly on all of Hello! Project, so I hope she's careful.
12AnonymousNov 2, 2026 12:42
I heard you can only buy mopeds secondhand these days.
13AnonymousNov 2, 2026 12:42
Just, please — no drunk driving, no running red lights, and no hit-and-run.
15AnonymousNov 2, 2026 12:42
A Hayabusa or ZX-12R would really suit Sato-chan.
17AnonymousNov 2, 2026 12:44
A crimson Z-II would suit Ma-chan perfectly (riffing on the "Crimson ___" meme from the Attack on Titan theme song).
18AnonymousNov 2, 2026 12:45
A female idol on a Harley-Davidson, lmaooo
19AnonymousNov 2, 2026 12:46
I want them to start a JPR touring club — Rikako and Aarii seem like they'd join in.
22AnonymousNov 2, 2026 12:54
Sato isn't that tall, is she? Well, maybe something around a 250cc would work.
34AnonymousNov 2, 2026 13:03
Re: #22
I think she said she's able to right a big bike on her own if it falls over.
23AnonymousNov 2, 2026 12:55
She's not gonna pass the written exam, is she.
28AnonymousNov 2, 2026 13:02
Re: #23
If I remember right, she failed it over and over before finally passing. Didn't she also have a boat license?
24AnonymousNov 2, 2026 12:57
Ma-chan, in character: "'Gonna ride,' right? Cashing in that payout on 'Invincible Yuuki'" (a riff on horse-racing betting slang, playing on her name)
26AnonymousNov 2, 2026 13:00
She's been riding pocket bikes since she was a kid — a born rider.
30AnonymousNov 2, 2026 13:02
Motorcycles are dangerous, maybe she should reconsider…
31AnonymousNov 2, 2026 13:03
This isn't even recent news about the bike anyway.
33AnonymousNov 2, 2026 13:03
If Ma-chan had been born a guy, she'd probably be even more successful by now.
36AnonymousNov 2, 2026 13:05
An idol who can handle a 1200cc bike, plus she's got a boating license — a total license collector.
37AnonymousNov 2, 2026 13:06
I wonder if her dad's snowmobile is still around.
38AnonymousNov 2, 2026 13:07
Her dad's probably got a jet ski or something too.
A video of Ma-chan riding what looks like a mini bike?
43AnonymousNov 2, 2026 13:11
If she can actually ride, she should show it off in a music video.
46AnonymousNov 2, 2026 13:19
'Not a moped (50cc)' = new-category 125cc — that's probably the punchline here.
48AnonymousNov 2, 2026 13:20
Miki Fujimoto got into two collisions and everyone just shrugged it off, so Sato will probably be fine too.
52AnonymousNov 2, 2026 13:22
Isn't the word that Harley-Davidson's in pretty rough shape these days? I've heard the dealerships barely function anymore. Though maybe some decent shops still survive out in the countryside.
53AnonymousNov 2, 2026 13:23
Surely she's not riding something huge, right?
55AnonymousNov 2, 2026 13:24
I vaguely remember her saying her dad's bike was a Yamaha or something. A Serow would really suit Ma-chan.
56AnonymousNov 2, 2026 13:25
Maybe a PCX150?
61AnonymousNov 2, 2026 13:32
Re: #56
Why secondhand? It's a 160 these days.
59AnonymousNov 2, 2026 13:29
Can a woman who's only 150-something cm even get her feet flat on the ground? That's the first thing to consider when picking a bike.
60AnonymousNov 2, 2026 13:31
What if Ma-chan starts rolling up to the dressing room on an 1800cc Harley-Davidson, like the one Natsu Ando rides?
62AnonymousNov 2, 2026 13:33
My ex was about 150cm and rode a Harley. She said she somehow miraculously managed to pick it back up — but only that one time.
Background and Talking Points
Yuuki Sato is a former member of Morning Musume.’14 who now belongs to the Hello! Project idol group Juice=Juice. She has previously spoken publicly about failing the written driving test multiple times before finally passing, as well as holding a boating license, which likely explains the anecdotes raised in the thread. Under Japan’s Road Vehicles Act, “moped” (gentsuki) technically refers to bikes of 50cc or under, but a revised classification means bikes up to 125cc can, under certain conditions, also be treated as mopeds — a source of confusion in the discussion. Within Hello! Project circles, fellow idol Miki Fujimoto is known to have been involved in two past traffic collisions, which is part of why idols owning vehicles or riding motorcycles tends to draw safety-related attention. The various model guesses raised in the thread — Hayabusa, Harley-Davidson, PCX, and others — are all speculation; no information confirming the actual model has been officially released by Sato herself.
