:lol: :lol: Well extremely unlikely my o_O :o ....it can be done for under a grand,will be faster than any 250 and very most 300's with even better fuel economy than a stockish 125...well my stockish 125 anyway,not to mention of how much fun it is.

I bought the 2015 pcx 150, US version expecting it to go 70 mph for short bursts, and to cruse easily at 60 mph. What I got was a peppy, in town scooter that hits the rev limiter at 63 to 64 mph, which is a bit scary when mixing it up with cars and trucks on our Dallas area freeways driving at typically 63 or 64 or faster. While 60 mph is fine for me, I would like about 10 mph more to keep up with traffic flow. The 2015 pcx 150 is about .3 or .4 more hoursower than the 2013 model, but tops out 4 or 5 mph slower. In my book they built it with incorrect gearing.

Too bad the previous A1 standard in Europe held the original design back to 100 kph so they only started with 125cc's. A 170cc version with gears for a best case 75 mph/ 120 kph would be the perfect machine for everywhere. Still fuel efficient in crowded towns. And fast enough for the truck lane of any super highway.

the 2015 pcx has no trouble at all hitting the limiter at 63 or so mph. My 1970 model cb350 had a red line of 10,500, which it would not reach on level ground at top speed. That is how I would think it should be. With Max safe load, it should be geared to not quite reach max rpm on level ground. close but not quite there. It is a very stable ride at 63 mph except for the limiter cutting the power. I've read on this Forum, that an NYC variator and drive face will get 74 mph out of a 2015 PCX. I just wish Honda had built it that way as standard. Like I said, my dream was to travel non freeway highways at 55 to 60 mph, whiich it will do, but there is not enough reserve for the rare need.

Maybe on the speedo yes. Actual GPS speedo might be a bit below that at 71-72.

Thing about the 2015 model is that it's a bit tricky to do more than the simpler transmission mods. They changed the throttle body and the wiring for the sensor block, so you'd have to jump through some hoops to install anything other than the Takegawa 170cc BBK.

I'm not sure 70 mph is a realistic expectation on flat roads, as your engine would likely run out of steam at around 68 mph. Depending on body weight and riding style of course.

The weather cleared, so I took my unmodified 2015 PCX for a ride. Took mostly highway 5 north to Sherman, turned around and stayed on the 55 mph frontage road to US highway 75, while its' posted speed limot was 75 mph. However, after about 20 or so miles, there was road construction on the frontage road and I had to get on the freeway. Guess the road construction or something had caused the speed limit to be lowered to 65 mph, so I could pretty much flow with traffic, by backing off slightly after bumping the limiter at an indicated 63 mph. It wasnt that bad. I even had to slow down a few times.
Anyway, for now I will stay with the factory setup. The off freeway ride was enjoyable, largely because there was light traffic, and I had no trouble flowing with traffic there. Still will avoid freeways with 70 plus speed limits, unless they have frontage roads. Enjoyed the ride, and a couple guys at the truck stop, when I stopped for a snack were impressed with the scooter. I did note that while bumping the limiter, gas milage dropped to 79 mpg! So if I need to drive 65-75 mph, better just do it on a Forza or some other bigger ride. Around town it usually get at least 95 or better mpg indicated, my pcx that is.

Again, carefully analyze your wants and needs before spending money on anything.

There's no shame in trading the PCX for something with more power. If your highways are faster and you want to spread your wings, you'd need a little more juice. Might also be awkward if you get lost and find yourself on a faster highway O_o .

It might also be worth noting that 79 mpg is still up there in terms of fuel economy, as your larger bikes typically do 60-70 mpg at best.

But again, if you're doing heavy freeway riding, get a bigger bike. If your primary use is city riding, the PCX is the one for you. For me, the highways here have a speed limit of 50 mph, with only one at 60 mph.

I agree, having put in a Malossi CVT system and their exhaust the difference is remarkable.
I struggled with the choice of the Forza power and the nimbleness of the PCX and for me I found a happy medium.

Didn't you say 65 mph was the most consistent speed you could get on flats? I found that to be accurate short of engine mods. You could get 65 on flats, but you'd have no reserve left.

He could probably get what he wants with a bore kit, but that's not something I would advocate at this point on the new model.

I don't know what can be done with this information but i noticed the other day that my Honda lawnmower has a 160cc engine, and it was one of the smaller ones they offered when we bought it. Also, i have a friend that just asked me to help him with his son's gokart. I noticed that it has a 212cc engine. I know that we can't swap engines but it seems to me that we are running little engines as apposed to other standard, gas engine devices. I am thinking that these little engines must have room for improvement. If the BBK can bump them to 196cc it would solve a lot of performance problems, and it would turn a 153cc bike into a 200 cc bike.

True enough. I just wanted to put the brakes on when he mentioned going 74 mph, as I can only manage that downhill.

Okay, but as I recall, Yumi's 196cc kit is priced at almost $1200(and probably will be after shipping costs). $3449 + $1200 = $4649.

A new Honda CBR250R is $4199. The CBR300R is $4399. I believe you can get any brand new 250cc cruiser for that price.

Unless there's a specific need for the PCX(cargo, size, riding position), it makes more sense to just buy the bigger bike. For me, I'm not crazy about the hunched riding position, and a cruiser is going to be a PITA to fit in my parking spot.

Even with both gearing kits on the market (Kitaco and Yuminashi) with an aftermarket (Takegawa) variator, and a big bore kit, I still top out at about 75mph redline. It gets there quick enough, and still has power right up to it. I might mess with my variator some to see if I can get more speed out of it.

I can cruise uphills at 60mph, which is the main benefits of the kit. Highway riding in the city is fine, but I wouldn't ride highway outside the city. Everyone there cruises at 80mph. I'd get run over.

Not the variator, unless you're putting in sliders.

Any further speed gains IMO would come from a KN Planning torque driver, which has longer slots and would allow the belt to drop down on the rear crank between the pulley. If you can reach the redline now on flats, you should be able to make use of it. I'd recommend the steeper angle for smoother acceleration.

Should be this one IIRC:

Not badly priced either. That shouldn't be too hard to mount on the clutch. The spring isn't strong enough that I'd need a press, I'm fairly sure I could swap those by hand.

How much of a gain is typically had with the aftermarket replacement?

Hard to say precisely. I gained about 5 mph on the speedo with it, but I also went from the Yumi Speed Control vario to the Daytona vario w/sliders.
