Hello everyone,
So im officially a proud owner of a honda PCX 125 as of this morning!
I bought it second hand with less than 10k miles on the clock and only 1 previous owner with full service history!
Anyway, i got two (hopefully) simple questions.
Ive been going trough the manual etc... i know my bike requires petrol, what i am struggeling with however is what octane?
the garage i use has 5 different octanes, and on my old chinese bike ive always used the regular 95...
What fuel do you all reccommend as i want this bike to last a lifetime!
Second question: where do i find out what year this model is from?
Ive been googleing, but there is so mcuh conflictin information out there!
Cheers, Dutchy
Year and Fuel request :)

I am not crazy. Crazy people don't know they are crazy, whereas I know I am crazy, so therefor I am not crazy! 

Re: Year and Fuel request :)
As for Fuel, I always run the highest available in my area which is 91octane since its Fuel injected. You can definitely get away with lower octane but unless you are pinching every penny, just run middle or higher octane. Its a 10.6 compression engine. Nothing crazy but Ive always gotten good performance from higher octane on EFI engines and better performance with lower octane in carb bikes.
The title for the bike should have the year of the bike. Ive never met anyone that bought a bike without knowing the year,make and model. lol Look up the Vin number on the bike. That should tell you exactly what year it is.

Re: Year and Fuel request :)
I know what year it was registered first time on the road which is 21 feb 2018. I know the model nr, which is the WW125EX2H..
Problem is i dont know what year this particular model nr originates..

Re: Year and Fuel request :)
You don't need to know the year for fuel, they all use the same.
First reg in Feb 2018 means likely manufactured in 2017, but not guaranteed.
Depending which country your in it could be a 2017, 2018 or 2019.
As previously stated, the VIN will tell you actual year of manufacture.

Four decades on two wheels has taught me nothing, all advice given is guaranteed to be wrong
Re: Year and Fuel request :)
In San Diego there's at least one gas station that sells 100 octane racing fuel (VP Racing in PB). Anyone think that is a good idea for this bike? Mine is a 2019 model.
THANKS!
THANKS!

Re: Year and Fuel request :)
You are completely wasting your money for any octane above regular octane of 87 or so. Whatever is regular in your town, use that.

Re: Year and Fuel request :)
Use what the user manual suggests - which is not premium at all. I've been using Asda (UK Walmart) unleaded for near 7 years and although it's now %10 ethanol, I still am getting 131mpg on the meter and it's still very cold here early morning and late at night.
I've had just under 130 mpg and mid 140's mpg (UK gallon) real figures using trip miles and litres in, all using standard 97 RON supermarket fuel.
Bike has given excellent service.

Ha ha ha ha. Don't run 100octane. 87-91 is fine. These bikes are intended to run regular.
I run premium since I have intake and exhaust, so its most likely running lean, so might help with detonation prevention.
