Both the scooters compared in this article are newer variants of scooter models that have been sold in the Indian market for a while now. While Ray Z is an improvement upon the 110cc Yamaha Ray, the new Honda Dio comes with a slightly larger engine and improved fuel efficiency compared to the older 102cc Dio that has been available for years. Let us take a look at the tech specs of these two scooters first.
First the engine. The Ray Z comes with a 113cc single cylinder 4-stroke engine that delivers a power of 7.1 PS at 7500 RPM. In terms of torque, this engine offers 8.1 Nm at 5000 RPM. In comparison, the Dio is a 109cc engine that cranks up 8.1 PS at 7500 RPM and 8.74 Nm torque at 5500 RPM. Clearly, the Dio is the more powerful of the two scooters. In terms of dimensions, the Ray Z is slightly longer (1835mm vs. 1788mm) whereas the Dio is a little wider (707mm vs 675mm) which I think will give Dio riders a much better balance and control over their scooters compared to the Ray Z. The Dio, at 110 kg, is also heavier than Ray Z by 6 kgs. The bikes are priced in the same bracket. While the Delhi ex-showroom price of Ray Z is Rs. 49105, the Dio is available at Rs. 47928.
The new Ray Z is a model that is targeted at the male audience and given that Dio is a heavier bike, this is popular among men as well. According to Honda, the new Dio not only comes with a larger engine compared to the earlier model, but also offers 15% better FE. They claim that under standard conditions, one should be able to see 55 kmpl. The Ray Z on the other hand has a slightly lower manufacturer claim. Unlike the 62.1 kmpl claimed on the original Yamaha Ray, the male-targeted variant is expected to deliver 53 kmpl under standard road conditions.
As any one following this blog will know, the standard condition mileage reports are mostly for bragging rights and the fuel consumption on actual roads are starkly different in many cases. So let us take a look at what various test rides and customer feedback reports have got to say. We do not have too many common points of reference but MaxAbout has reviewed both these scooters and notes that the Dio 110cc can provide its customers an FE of between 40-43 kmpl on city roads. In comparison, the Ray Z will give 40 kmpl. There doesn’t seem much to choose from here.
Next up, the user reviews site, MouthShut. The customer who reviewed Ray Z on this website rated the bike 3/5 in terms of FE. He reports 41-42 kmpl pre-servicing. There are not too many reviews of mileage for the new Dio either but the user who did report this on MouthShut says he was able to see just around 30-35 kmpl. That is very likely an outlier and do not base your purchasing decision based on this number.
The Yamaha Ray Z has also been reviewed by a couple of other websites like BikeWale and IamaBiker. Both these bikes unanimously report a figure of around 43 kmpl on city roads for this scooter from Yamaha. The Dio on the other hand has received fuel reports from websites like ZigWheels, Top Gear and BikeDekho. ZigWheels reports a number close to what MaxAbout had quoted: around 40-43 kmpl. BikeDekho on the other hand reports the highest figure of over 50 kmpl under city conditions which I think is extremely optimistic. Top Gear reports a lower, still positive rating of 48.5 kmpl on city roads. It is not a good idea to trust customer reports on websites like Olx and Quikr since the sellers here have an incentive to crank up the actual mileage offered. Surprisingly, Dio owners here quote a number between 40-45 kmpl on city roads.
The bottomline is that except for a couple of websites like ZigWheels, most reports of mileage hover between 40-45 kmpl for both the scooters. I have tabulated all the reported figures below.

Overall, all other factors like after-sales and personal preferences being the same, I think Dio is a slightly better scooter than Ray Z. It is priced a little lower, has a much more balanced framework and offers a mileage that seems slightly better than the Ray Z. What do you think?
