Re: PCX top speed

I weigh between 165-170 depending on the week lol. The Givi 322 is the small Givi screen. I have a large screen, however I'm saving it for colder weather.

The PCX125 is generally limited by both power and redline to about 62 mph. You can go longer with the gearing via a bigger tire or sliders but without more power it might not go any faster on a level road. My PCX150 would do about 66 mph when new. That started to dip to 63 with some belt wear in. And is mow back up to a redline limited 69 with 12 gram DrPulley sliders.jayj11pcx125 wrote:I am looking to bump up my pcx125 top speed capability by a few mph. I
sendler what are the stock 150 slider weights? and are you using the stock variator with the dr pulleys?sendler2112 wrote:The PCX125 is generally limited by both power and redline to about 62 mph.

Its best to replace vario for top speed increase.Sliders wont increase top speed much at all and if replaced weight for weight with stock rollers then its almost waste of time if done for performance cause. Sliders are little bit better than rollers but not that much by and best thing about them is they will last well over 25+k without needing maintenance. If anyone wants optimum performance out of their 125/150 Pcx then the weights have to be set for 8k rpm wot acceleration. It really brings out the best out of the Pcx engine without adverse fuel economy effects (thats for stock and aftermarket varios). Now someone will say 8k RPM?! But remember thats only on wot when maximum power is needed otherwise normal riding half throttle takeoffs rpm would sit at say 6.5-7k rpm and thats more than enough to stay ahead of traffic from the lights and cruise..If i remember correctly stock weights on 125cc (15g) WOT is 6900rpm initially and then torque driver drops them to 6200rpm at 60kmh...makes the big power drop between 60-80kmh where after 80 starts picking speed up again.. So you're always full throttling to stay ahead of traffic in stock form and full throttle all the time means more fuel...Also Kitaco rear spring is very good upgrade,its shorter and not that much heavier than stock spring so it doesn't impede top speed performance and will make throttle response always snappy. It will also reduce the mid power drop that the torque driver characteristic displays with stock spring..dasshreddar wrote:sendler what are the stock 150 slider weights? and are you using the stock variator with the dr pulleys?sendler2112 wrote:The PCX125 is generally limited by both power and redline to about 62 mph.

I'm using the stock variator and the stock weights for my PCX150 were 18 gm. The DrPulley sliders are 12 gm and now pull at around 8,000. I also installed a tach. This was the only weight I could buy at the time and I thought they would be too light but after living with them I wouldn't make them heavier. My fuel economy continues to rise to about 103 mpgUS as I go past 5,000 miles on the bike.dasshreddar wrote:sendler what are the stock 150 slider weights? and are you using the stock variator with the dr pulleys?
Changing the rear pulley to one with a different torque slot won't change the engine power. Aftermarket front and rear pulley sets can be set up to operate the trans at a higher rpm when pulling so you are running at the power peak for better acceleration and they also give a longer final ratio for a faster top speed. Down hill at least for 125's since they are generally limited by horsepower to 62 mph on the flat and by the rev limiter to 62 when going down hill. Two free mods to increase power are removing the snorkel from the air box and drilling the exhaust. Both mods let more noise out but give a slight increase in power below the hp peak once the fuel computer adapts.Mgalutia88 wrote:So what's the theory behind the torque driver?
Stock torque driver has banana curved groves which offer resistance initially up to 60kmh (35mph) for faster takeoff and then without riders control shift up to say from 3rd gear straight in to a 5th. Its speed dependant and there is nothing one can do but ride it out till you get back in to a optimum power range rpm. Usually 'normal' person wouldn't even notice or be bothered with on flat terrains but when it comes to inclines (hills) or windy days or overtaking it can peg your acceleration right down and bog you on the hill climbs. There is nothing worse than feeling of driving up a hilly roads and you decide to shift from 2nd in to a 4th or similar..Unfortunately that is completely out of ones control on auto cvt in stock set up. However you can buy aftermarket torque driver with straight groves which don't allow the cvt to shift up too early but peg your rpm to the weights setting and gives you the total control of your rpms via the throttle input,so you control how and when you want your maximum power out of the engine and transmission..Once you try you will never go back to stock banana shape groves.Also i need to say it will not give you more top end,for that as i have been saying all the time is one will need to piss of the stock vario and get aftermarket one. Stock 125cc with aftermarket vario has enough power to pull 120kmh easy all day everyday and up to 125-130 on a highway or perfect road conditions...So 150 should have no problem doing any of those speeds with even with more ease.Mgalutia88 wrote:So what's the theory behind the torque driver?

Webike just updated their products available and this is just listed as of today..Pcxdemon wrote:Stock torque driver has banana curved groves which offer resistance initially up to 60kmh (35mph) for faster takeoff and then without riders control shift up to say from 3rd gear straight in to a 5th.

KnPlanning has torque driver on Webike thats real good quality and fairly cheap at around $70...im using it and its very good!
The way to see and feel the overdrive kick in or the slump is to take of in full throttle up to say 60mph,watch your rpm lift to 6900 initially and then taper off to say 6200 or so half way thru the speed range. You can also hear the engine ease off before starts to build the sound up again up to 60mph. (stock pcx set up)sendler2112 wrote: At 35 mph it goes from 5,800 rpm at light cruise, right to 7,800 when I crack the throttle and drifts slowly up above 8,000 as the speed increases. I still have some active control at 50mph where it will cruise at 7,000 and crack up to 7,700.
This definitely never happens on my bike. I will have to capture some video of the tach and speedo as it hard to take notes while you are riding.Pcxdemon wrote:

It's the same shape as first gen 125.sendler2112 wrote:here is the torque slot in my stock PCX150.

Wow...!! That would perfectly make sense if we had say 50+hp machine, I wouldn't even care about any of the mods on that thing. But on 10hp scooter every little thing counts to get every one of those 10hp to the wheel and eliminate any losses thru the transmition..besides makes it a great hobby of sorts...you you wrote:Ffs its only got 10hp

I think he is saying that if the PCX had 50 hp, we wouldn't feel any need to modify it.you you wrote:

It's got ten tweenyweeny hp
