Yamaha Mio 125RR Liquid Cooled Vs. Yamaha Mio MX of 5 Years Ago

Yamaha Mio MX vs. Yamaha Mio 125rr Liquid Cooled.

I mentioned we gave our Yamaha Mio MX that was 5 years old to my wife’s elderly aunt – 70, that was still riding an old Yamaha motorbike, but I mean OLD motorbike – at maybe 20 years old.

We decided, after driving a car in Thailand, that we need a motorbike to get around for the majority of trips the car is not good in traffic.

We are looking at the Nouvo 135 Elegance and the Mio 125RR Liquid Cooled motorbikes at the moment. We already dropped the Click, Airblade, and other bikes (Suzuki) for lack of horsepower and top speed.

Apparently, and I didn’t know it at the time, I was spoiled with that little white Mio MX of 2005. That thing had power enough in the lower gears and speeds – that I didn’t often want more. It also had a top end of 115+ when we first got it – which died away as the years went by. We got an engine overhaul around 75,000 km which gave it all new life – and it was perfect again – even faster in the lower gears than it was originally – and a top end about the same.

I don’t know what the guys at Yamaha did when they rebuilt it – besides replace damn near every moving part in the engine – but, the bike worked better than new after they fixed it.

On to the Yamaha Mio 125RR Liquid Cooled motorcycle that is the newest they have.

We rented one today and I just returned from trying it out.

From 0-80 maybe 85. It’s nice and fast. I can’t believe this automatic bike is as fast as it is. It’s nice. I was excited to go for top end. It was difficult to get it off 90 kph. It was really difficult to get it off 100 kph. It was literally impossible – sitting normally, to go faster than 107 kph. Ducking down I got another 3 kph.

Going down a very steep hill I got it to 112 kph.

So, not at all happy with that performance at all. Is there a rev limiter on the top gear? I think there must be. It just doesn’t make any sense unless the gearing is totally favoring the low speeds and makes no effort at giving a good top speed.

Other than top speed, the bike is an upgrade from our old Mio. It has foot pegs instead of a small plastic step a passenger is supposed to put feet on. It has room under the seat for your helmet. It has seat that unlocks from the ignition directly… It has a nicer shape and some more power under 80 kph.

It looks like we’ll be going for the Nouvo 135, but we’ll test one first. Maybe they squelched the top speed on that one too?

Anyone know?

Update re: Nouvo Elegance 135 and Mio 125 – both of the new models…

Two weeks ago I rented a Nouvo Elegance 135cc – newest model and took it 300km south to Satun the other day, and back of course. I do like it for long distance travel. I could do without the bump in the seat – it’s ill-placed and I couldn’t sit how I wanted to – but, other than that I have no complaints except – of course – not fast enough, but if you look at what it’s competing against – for long distance travel over 100km – it’s the best of the best.

We have a 125cc MIO – new one. The seat is worse with that stupid bump in it and nobody has a padded flat seat that I can find – for the new Mios. They have a weird design. The MIO is more twitchy and you feel the bumps more.

The Mio 125cc is as fast as the Nouvo under about 90 KPH. It’s lighter. Torque is good – about same as Nouvo. Top speed for the Mio is somewhere about 110. For the Nouvo – about same – coming off a downhill the Nouvo can hold 115KPH, but on the flat it can’t get more than 112. I’m nearly 80 KG.

Oh – the Nouvo tires didn’t feel very nice on windy roads. They felt soft like they were going to roll off the rim. Not a good feeling. I had a Suzuki Raider 150cc for almost a year that I put Michelin tires on and they were really nice for cornering.
The Mio for cornering is better than the Nouvo – feels tighter, less risky to make sharp curves.

For getting around town – nothing beats the MIO – it’s fast enough and even has a cool sound to it – a deeper growl than other bikes without modification to anything.

If you’re going long distances often – it’s no contest, get the Nouvo 135 or 150 if they have one.

Just a note about the Honda PCX I think it’s called… I think they’re ridiculous looking, and remind me of the old 250 motorscooters back in the USA, “Helix” which I thought was a joke.

  1. Hi, I am in Phuket and purchased a 135 Nouvo in December..also a hired the older Mio as mentioned a few months back which was pretty tired and not suited to the hills of Phuket. I think it needed an overhaul as yours did. With the Nouvo,2 up combined weight 140kg, it easy hits 90k/hr on flat stretch between Kathu and Phuket Town, and that is not full throttle. I haven;t stretched it further than that but other web posts say 110k/hr is doable. The bike is good but not as stable as a PCX which would be my pick by far, except for the extra cost and was unavailable at time of purchase.
    My only real gripe about the Nouvo is lack of cutout switch linked to the side stand, Yamaha just cant be bothered to add this important safety feature.
    Final note compared to latest Click I, the Nouvo is rougher handling and I find the Click I a smoother, more comfortable ride, though it doesnt math the Nouvo for top end, of course.

  2. the nouvo elegance 135cc will blow you away compared to a fino or a mio,its got bigger wheels, much more torque and stability ,i dont drive mine gently ,usually open the throttle 100% and can overtake almost anything ,only the “big bikes” are faster ( provided the driver is sharp on his gear changes )
