The vehicles from Aprilia are mostly loved by many people in Nepal because of the great body design, standard performance, and its technical specifications and now it has launched two new vehicles Aprilia SX 125 and RX 125 in Nepal which are both priced at Rs. 7,99,900.
So part of the SX and RX cost-cutting comes from using the same 124.2cc, four-stroke, four-valve, double overhead cam, single cylinder motor as the RS125 and Tuono 125 – the engine covers are slightly different, but the casting and internals are identical. In fact, the motor has been around for a year – built by Zongshen in China, it’s the same unit that once powered Derbi’s GPR125.
And, given what it’s got to work with, it’s not a bad power unit. In the absence of an adults-only quantity of horsepower, the next most important engine characteristic is being able to have the arse revved off it – and with no tacho to distract you, both the SX and RX will happily spend most of their lives swapping between fourth and fifth (inclines and headwinds limit the usefulness of sixth gear), bouncing off the rev limiter downhill. Aprilia say engine power peaks at 10,700rpm, which is crazy high even for a weeny 58mm diameter piston zipping up and down by 47mm every few milliseconds.
But the balance-shaft motor is refreshingly vibe-free – 50 miles or so pretty much flat stick on the RX felt fine, with no finger numbness – and both bikes will gun along at 70mph, eventually. Of the two bikes, the RX is nippier off the line; the SX sports a massive 62-tooth rear sprocket but the down-geared RX beats it with 69 teeth. That’s almost more than all the Bee Gees put together. The difference in gearing is meant to compensate for the RX’s larger rear wheel diameter, but in reality the off-road bike has the edge on acceleration – and that matters a lot on a 125. Aprilia SX 125 is available in two graphic variations like: Red Fun and Black Drift, while the RX 125 will be only available in Red Fun.
