The Honda PCX / Forza / ADV150 / SH Forums

You should get a phone mount and use the GPS on your phone to get accurate speeds.

Variator (properly tuned), Intake, exhaust, taller tires and windshield. Should get you to 70mph but not comfortably. These bikes are not designed to go 70+ for long stretches of time and that's coming from someone that had a PCX that did 70 pretty easy (top speed 78mph for me).

The diameter is larger than the stock tyre. Gearing and speedo/odometer accuracy change. The Speedo reads about 2-4miles lower at 55mph. That's a small "negative" if at all for the benefits of how the bike feels at speed. So much more stable. Gearing wise it's only a positive bc you get h...

You should of upgraded to the larger size City grips. I put over 6k miles on mine and they were still like new. The bigger size tires are a game changer. Stock size is horrible. I checked the bigger size against the standard size on Errol's Tyres https://www.errolstyres.co.za/odcalculator , going t...

THe bigger size tires are a game changer. Stock size is horrible.

This sounds like a post that was on the PCX Facebook page.

120/70R14 front
140/70/14 rear

Thank you later. They fit with no clearance issues.

As expected. lol

Yeah even if its 670Watt output at 5k RPMs, you are never that low of RPMs ever cruising so the output is even higher than that. Maybe more in the 1k watts range.

Can anyone verify the 120/70/14 will fit without rubbing the fender or causing problems?

It will fit, no problem.

I have the magical Non-Existing 2017 PCX. It's a 150. Bone stock bouncing the limiter, was 64MPH (all GPS Verified). Added intake and exhaust: 64mph (intake and exhaust doesn't really increase top end. CVT and gearing determine top speed, I&E just improves acceleration) Added a Variator/Drivefac...

My bike fell over and destroyed the taillight and rear quarter. It cost me about $250-300 total.

I wonder how much better the newest model performs.

From what I gathered, the newer ones are more efficient. Better top speed bone stock.

I just did some research, and it appears that the 2019 is different than the pre-2018 and post 2021 models. So strange. So, if I had to guess, with the 2019 for whatever reason, Honda went with short gearing, but Tall Variator, and on older models like mine, they went with tall gears and shorter Var...

I have my bike tuned for hard acceleration. I like it to scream off the line to beat traffic hence the super light weights. My MPG is down into 75mpg range bc of that but I'm content with that. Get a gram scale and measure your weights. I thought the stock weights were in the 15+g range. Usually, 13...

What size rollers did you install (Gram specific). Did you gain ANY more top end at all? What was your top end before, bone stock? I have that same exact setup on mine. I immediately saw an extra 7-10MPH top end granted I have a 2017. Get a TTO tach. Helps with tuning the variator. I run 10.5G slide...

Personally, I think those plastics on the bars looks hideous. Then again I think the stock bars on all PCX are ugly (hence me changing out my bars to Z-bars.

I would suggest just removing the plastic covers and exposing the bars to use a traditional Bar Mount. Or you can notch the plastics.

I am almost decided to trade in my 2021 PCX for the 2025 - just so that I can get the 6-year Honda warranty extension. My son rides this in college and I need trouble free riding for him. I know these scooters - just about nothing goes wrong but I need some peace of mind. The dealer told me he has ...

I feel the stock rear shocks are the softest shocks out there. Most aftermarket would be stiffer, I could be wrong.

I run some Takegawa lowering rear shocks. They are stiff but I run them bc they are shorter than stock which is what I wanted since I lowered the front.

Spray everything down with some WD40. Spring, bounce it, spray, bounce it. Should be easy to isolate the issue. Then once you find the issue, you can just wash off the WD40 from where its not needed and then use the Silicone spray.

Revzilla has both size tires in the City Grip 2.

If a shop ordered the wrong tires once, I would never use them again. I always buy my tires online myself sized to match what's on the bike. Partzilla is my go-to for everything scooter related.

I know the newer PCX has a 14 front 13 rear. Unlike the 14 front/rear like older model PCX's.
