Help me understand roller weight/size

[nemesis98]

I am looking to add new roller weights, and just am wondering what all the different numbers mean?
I understand the weight (in grams), but what about the other numbers? 18x14? 16x13? 15x12? huh?

I'm thinking about changing out to Dr. Pulley 11 gram rollers, just need to know what the right ones will be.

Mainely Scooters has them listed on Amazon, but all it says is: 'Size: 15x12, 16x13, 18x14 Set of 6. Lasts longer than standard roller weights Excellent Heat Resistance Low Friction / Low Wear' in the product descrition.

Help!

The size is the physical size of the roller. 16x13 means the roller is 16mm wide and 13mm long. Different variators need different sizes. Most 50cc use 16x13 and most 150's use 15x12. You need to know what is in your scooter though as some mfg's do use wrong size rollers.

Hi Greg
Excellent explanation though i differ on one point
There not the wrong size rollers my 50 cc scoot uses 19x15,5 roller weights and though different from the norm they are what my manufacturer decided to use
So instead of using the term wrong how about using the term different
Heres a listing of different scoots stock roller sizes

Take care and ride safely dear friend

Now I have found most gy6 150cc use 18 X 14. This is just another case of know what you have before you make a change or order something.

Thanks for the info - now just one more question.

How will I be able to know what size I currently have? Will it be stamped on the rollers themselves, or will I have to measure them?

Thanks!
