Grom

So without going back and reading 157 pages if I had a stock 24 grom and wanted to race with WERA what would be the best options to be semi competitive. brands and rough pricing would be ideal.

I assume suspension (ohlins?), ECU, tires, exhaust would be the minimums, maybe rear sets? gotta be able to carry corner speed!

 

if you change the intake and exhaust, you can get a flashed ECU from DHM Motoring. rearsets seem to be popular for the Grom series. Ohlins suspension is the choice in the paddock, but many Grom enthusists like RaceBros as well.

 

I know I'm late to the game (story of my life) but after last weekend at Tally the Grom looked fun. Perusing my local ads I see 14-24's all over the board, but generally $2500-$3400. Is the 2022+ with the 5 speed really that much better? We may try the Grom Cup but it's more for a pit bike and general around town goofiness.

 

Why do you want a slower goofing-aroundbike? You have to buy to buy the 5-gear version......... because there's no 6-gear model!

 

Hard to believe this thread is almost 10 years old

 

21+ are supposedly better all around and have slightly more power. they have a known trans whine issue that is commonly discussed on the FB groups. if you're looking for a purely street/pit toy, the hot setup is a 17-20 with a CBR 250r/300 swap. find a donor bike and swap over the motor, exhaust, harness, speedo and a $200 bracket kit.

 

I had that setup (300 swapped into a 2018 chassis) and got rid of it - the issue is the injector and how it mounts up to the CBR engine. I tried some of the 3D printed ones that they're selling on FB, but nothing seemed to work. It makes fuel delivery and getting that dialed in a real bear......

Buuuuuut, it could also do 100 mph with my fat ass on it (which to be fair was quite SKETCHY on those 12" tires with that wheelbase).

If I were to do another Grom, I'd do something like yours and get it built to the max with the stock engine.

 

Tires and corner speed question from you?

 

Well I joined the club. Found a 23 with 1K miles for 3 grand. It's practically brand new. Let the fun begin!

 

It's a sad state of affairs when you have to squeeze a Grom sideways in your "truck" bed

 

My truck does just fine.

 

Its just jokes... my truck is a Venza. Congrats on the Grom
