    How different is Yamaha’s newest baby retro from its elder sibling? We delve deeper to find out

    Yamaha recently introduced in Europe its smallest motorcycle under the XSR family, the Yamaha XSR125. Since it is based on the popular Yamaha XSR155, we couldn’t help but wonder how different the two motorcycles are. Here’s our analysis:

    What’s different?

    The most obvious difference lies in the powertrain. As their names suggest, the Yamaha XSR125 and the XSR155 cater to the 125cc and 150+cc segments, respectively. Take a look at the table below:

     

    Specifications

    Yamaha XSR125

    Yamaha XSR155

    Engine

    124cc, single-cylinder, liquid-cooled engine with VVA

    155cc, single-cylinder, liquid-cooled engine with VVA

    Peak power

    14.9PS at 10,000rpm

    19.3PS at 10,000rpm

    Maximum torque

    11.5Nm at 8000rpm

    14.7Nm at 8500rpm

    Transmission

    6-speed

    6-speed with assist and slipper clutch

    Kerb weight

    140kg

    134kg

    Power-to-weight ratio

    106.8PS per tonne

    144.08PS per tonne

    Disc brake sizes front / rear

    267mm / 220mm

    282mm / 220mm

    It is worth mentioning that European safety and emission regulations are stricter. Hence, the Yamaha XSR125 comes with a dual-channel ABS as standard along with a Euro5-compliant engine. The ABS module, along with the extra emission-restricting components, could be why the smaller-engined XSR is 6kg heavier than its bigger sibling. So the extra heft and the relatively low output have significantly impacted the bike’s power-to-weight ratio. 

    Additionally, the XSR155 gets the advantage of an assist-and-slipper clutch, ensuring easier lever operation and preventing the rear wheel from locking up while downshifting hard. And thanks to the extra performance, the Yamaha XSR155 benefits from a bigger front disc, ensuring better stopping power. That said, there’s no ABS, not even as an option.

     

    Dimensions

    Yamaha XSR125

    Yamaha XSR155

    Ground clearance

    160mm

    170mm

    Seat height

    815mm

    810mm

    Fuel tank capacity

    11 litres

    10.4 litres

    The slight difference in the fuel tank capacity may have also contributed to the extra heft. Interestingly, despite having more ground clearance, the XSR155 gets a 5mm lower seat. This should be helpful for shorter riders, and the added ground clearance should also help to explore the trails. 

    Another major difference between the two bikes is the colour scheme. That said, both are eye-catching, irrespective of the body paint. Both bikes have block pattern tyres from the same brand, but they’re slightly different models. While the Thai-spec Yamaha XSR155 rolls on IRC Trail Winner GP-211, the Euro-spec Yamaha XSR125 is shod with IRC Trail Winner GP-210.

    What’s not-so-different? 

    The Yamaha XSR125’s design is pretty much the same. If it weren’t for the different colour scheme(s), it would’ve been easy to mistake the smaller bike for the XSR155. The front inverted fork, rear monoshock, 17-inch alloy wheel design, and even tyre sizes (110-section front and 140-section rear) are the same. Also, the 1,330mm wheelbase is the same on both bikes.

    The two motorcycles are built on the same deltabox frame, linked to an aluminium swingarm. They are equipped with an all-LED headlamp, LED tail lamp, bulb indicators, and a full-LCD multifunction instrument cluster. 

    All in all, Yamaha should manufacture the XSR125 fairly easily, considering several parts, including the chassis and some features, are shared with the XSR155. However, instead of bringing either one of these to India, Yamaha plans to launch the FZ-X, which is based on the proven Yamaha FZ-Fi platform. Check out all the details here.
