The Honda PCX / Forza / ADV150 / SH Forums

Saw a 2018 PCX up close today at the parking, first thing I noticed is that the tires are slightly wider.

I then checked online for its specs..

I found out that the new pcx 2018 comes with 100/80 - 14 front and 120/70 - 14 rear Michelin City Grip tires..

Now, I want to change my tires to that sizes too..it just look balanced and good in my eyes.
Who else loves this?

Interesting discovery. I'll be needing a new tires soon and those sizes might be an option, not sure if they will fit though.

They may now have introduced what some members here have done - fitted slightly wider tyres. On the normal PCX, I believe the rear plastics needed some modification to fit the wider tyres. As usual, there was discussion whether wider tyres have benefits - it would seem like with motorbikes, you gain stability and grip, but others said the tyre choice for the normal PCX was ideal and Honda as always got it right

Thanks for the informative response iceman, ill search through the forum for more info.

I'm running 110 at the front and 120 at the rear. No modifications were needed at all, and the above specs should be fine on any stock PCX.

Slight mods (in fact a some spacing of the rear fender) needed if someone wants run 140 at the rear.

To put the 140/70-14 rear Michelin on PCX you need to make this simple modification.

If you like wider tires you can put the 120/70-14 on the front without any modification.



Here are the results of oversized tires/tyres

1. Speedometer will be off a couple miles per hour than actual, GPS will confirm.
2. Loses 4 mile per hour off top speed due to increased mass turning.
3. Stability increases, softer ride and a bigger bike feel in my opinion.
4. On rare occasion a pebble ridding the tread will rattle between the front fender and tire/tyre.
(this does not happen on the rear but its very startling the first time you hear it)

Bought my set of city grips from the superstore, never going back to stock rubber.

Not a good idea, it will result in a slightly reduced top speed bcause the new tyre size has a smaller diameter.
Also until you confirm that the new rim is the same width and the steering geometry is unaltered on the new model, you will not be able to determine the suitability of the different size tyre for your older model.

I don't think we need modifications to fit (100/80F ,120/70R). Will confirm with Honda here

I'm just glad because Honda will now have those sizes in stock for sure. Before, I think I saw only 140R and 120F Michellin, which are too big for a stock pcx imo.

I am not a tire person so I will need for someone to explain the numbers to me. The one thing that I do know is that City Grips are much better than the stock tires.i do know that 14 is the rim size, but that is about it.

So, with that in mind, would someone please explain what the numbers mean, please??

The numbers on a tire are the width(in millimeters) and the sidewall aspect ratio(in percentage).

So, a 120/70 tire would be 120mm wide and the sidewall height would be 70% of the width or 84mm tall.
Hope this helps.

Here's a video on that Mel.
I'm sure many of us wonder the same thing. We inflate our tires and see letters and numbers all about them. Seems strange what the heck are they?



Then there's the DOT Code: (Dept. of Transportation)

I’m running standard size Bridgestones I really like how fluid the bike handles.
I guess wider tyres might slow the steering up a bit but I like it as it is and with counter steering it feels well planted in corners.
Aesthetic reasons I can see why people prefer wider tyres

I can't seem to find the tire of that size. I hope the new PCX makes it to the US at some point, so that we can have access to those sizes.
The bigger sized tires just look too big, imo. I also wonder what the top speed will be with the tires of the new PCX.


Thanks everyone for your informative response.

A 4 valve head would be a worthy update. Please Honda please

Not really.
Its already super economical and delivers enough power for its intended purpose.
Maxing it out to the legal maximum allowed for a 125 of 11kw will still leave you unable to keep up with A-road traffic.

Oh but what an 11kw that would be.

Enough to transport us all to the heavens. Or boil a kettle.

We’re not sure yet.

update: the 2018 PCX is using a much wider wheel size than the previous years PCX models.

Honda said I should upgrade to wider wheel size if I want to use the new 100/80 - 14 front and 120/70 - 14 rear.

I doubt it is really necessary. But at least now we have more options..

Guys, pcx 2018 model;
Shift the original rear tyre 120-70-14 to front.
Put in new Pirelli 140-70-14 tyre. It's a perfect match.
No modification required. Much better riding before and after.

When it was time to change my front tire recently I thought about the new sizes and tried to find them online.
Michelin City Grip 100/80 - 14 front tire size sounds great, but no one has them in stock, it seems. So I went with the default size the mine takes normally...90/90 -14. Well, at least it has Michelins on it. I will probably sell the bike long before these new ones wear out.

My wife is already talking about selling hers, since she hasn't put more than 20 miles on it since her accident in 2015. I have put most of the ride miles on it since then. It rides beautifully, and runs great. Still, how long can someone swap between two identical bikes before wondering if it is worthwhile?

I thought it was not wise to switch front/back scooter tyres (or at least I though I had read that reply someone hear some time ago)
