I don't know if the thread exists yet or whether the subject has been beaten around or not.

But does anyone know if there another production Honda that the grom shares the same bolt pattern with for front rotors ?

So far we know the front sprocket is the same as the CRF50's and the levers are the same as the CBR250's.

Any clue on the front rotors ?

I'd really like to slap a quality brand two piece floating rotor on my bike when I do my brake upgrade.

Thanks
Scott

Not really an answer but the XR50 rear sprocket bolts have the same spacing as the Grom. FWIW

I have a REAL Braking wave front rotor for my Grom

Will rotor work with the front Tyga/Brembo setup. Where did you get it.
Thanks

They factory rotor looks identical to the pcx, not sure if those offer big brakes though

If the bolt patten matchup, any of these should bolt to the wheel

BRAKING : Wave disk [77321]

So that confirms the pcx/Grom match, shit I need some KN 260mm rotor in my life!

There we go ! This is the kind of information I need. haha.

yes the psx works on the front. pcx's didnt come with rear-disc, so thats why you are seeing vendors selling just the front.
i picked up a set of these: Lightweight Front Rear Disc Rotors for Honda Grom MSX125 USA Seller Shipping | eBay

Price is shipped. not bad at all from what i seen. about 10-15 more then what ive found in Thailand. After getting screwed over by KingKongSoap, i don't buy international anymore. so the extra $15 to buy them from that usa seller
was worth the cash to have them in 4 days lol

I know eventually they will come out with a bigger disc setup. Meanwhile this will do, and i know i'll be able to sell them alter for at least $80 used when its time to upgrade to a bigger disc setup.

I'm wondering what the max size rotor the Tyga bracket and a Brembo P32 can take. 220, 240, or maybe a 260mm ?

KN Planning : Black Big rotorKit 260 mm With support [PCX-13-BK]

MADMAX : WaveBrake disc 260 mm Type 3 [MM19-0293R]

I like this one the most right now though

Take this rotor and a p32 with the Tyga bracket to a machine shop and have them remake the Tyga to fit the 260, then sell me one of the brackets at cost for the idea lol

220 is biggest. I'm sure the guys at steady could make a bracket for a 240 or 260 rotor but why go bigger than a 220. You are just adding weight.

True that. Just need to pick out a nice 220mm rotor now.
