Yamaha – New XVS125 Drag Star

Yamaha – New XVS125 Drag Star

Yamaha – New XVS125 Drag Star:

 

Yamaha’s new entry-level V-twin cruiser

In the last few years the demand for 125cc motorcycles has expanded massively as new legislation in certain European
countries has allowed car licence holders to ride machinery upto 125cc.

Yamaha: The major force in the 125 class

Yamaha has been a major force in the 125cc category for many years, and currently offers one of the widest ranges of machinery available.

One of the most popular types of machine with new riders is the custom motorcycle, and Yamaha’s XV125 Virago is currently a strong seller in this important class. With its V-twin engine, low seat height and natural riding position, the smallest Virago has been one of the best ways to get started on two
wheels.

New Drag Star 125

Joining the popular XV125 for the new season is the all-new Yamaha Drag Star 125, a high quality V-twin cruiser styled just like Yamaha’s larger-capacity Drag Stars, and featuring a distinctive long and low chassis, raked-out forks and a real big-bike feel about it.

XVS125 Drag Star Engine

Reliable, powerful and economical 4-stroke V-twin

Like all of Yamaha’s Drag Star models right up to the top of the range XVS1100, the new entry-level Drag Star 125 is powered by a good-looking air-cooled 4-stroke V-twin engine.

Virago-based engine with 26% more power 

This ultra-reliable powerplant is based on the highly successful engine used in the XV125 Virago, and it has undergone a large number of significant changes which have boosted power by nearly over 26%.

Excellent performance with impressive economy

Running a bore and stroke of 41mm x 47mm, this economical engine delivers plenty of torque for cruising at lower speeds around town. However, the new Drag Star is also a strong performer out on the highway, thanks to its BDS26 carburettor equipped with a Throttle Position Sensor (TPS) which ensures excellent fuel economy and efficient combustion throughout the rpm range.

Uprated engine internals

The main changes which have boosted the Drag Star’s power output (compared to the XV125 Virago) include revised cylinder head porting, a higher 11:1 compression ratio, a new-design piston and modified intake and exhaust valves.

Quiet running

Other changes to the engine include reshaped cylinder head fins, thicker crankcase and engine case walls, and a new silent-running cam chain, making the Drag Star’s engine one of the quietest in the class.

Twin over-and-under mufflers

The Drag Star 125 is also equipped with a large-capacity air intake situated to the side of the engine, and is fitted with a pair of free-breathing over-and-under mufflers which run along the bike’s right side.

13ps @ 10,000rpm

These modifications work together to deliver 13ps at 10,000rpm, giving this beautifully-styled new 125 cruiser lively performance that will keep the rider and passenger ahead of the traffic in town, and will give this new 125 a strong cruising speed on the open road.

Improved shift feel

As well as the boost in performance compared to the 125 Virago, the new Drag Star 125 engine is also equipped with a needle bearing on the shift shaft, which together with a redesigned gear pedal and linkage ensures super-smooth shifting.

XVS125 Drag Star Chassis

Long and low cruiser chassis

Yamaha’s larger capacity Drag Stars are some of the best selling machines in the middleweight category, and Yamaha anticipate that the new Drag Star 125 will enjoy the same success in the entry-level class.

Raked-out front forks

What differentiates Yamaha’s XVS line from other models is the ultra-long and low chassis design and raked out front forks featured on every model from 125cc up to 1100cc.

All-new chassis

While the Drag Star 125 engine can trace its origins to the highly successful XV125 Virago, the chassis is all new, and has been constructed to the same basic design as featured on the larger Drag Stars.

The frame is of a double-cradle tubular design which ensures exceptional chassis rigidity, and the extra-long wheelbase of 1520mm accentuates the ‘stretched’ cruiser image.

35mm diameter fork tubes

Offering a generous 140mm of wheel travel, the Drag Star 125’s front forks feature large-diameter 35mm tubes which are protected from stone chips by lightweight guards – and to underline the front end’s heavy-duty appearance there is an extra-wide pitch of 200mm between the two fork tubes.

With its long wheelbase, massive-looking big-finned V-twin engine and beefy front forks, this is one machine that could easily be mistaken for a middleweight.

Twin shock rear suspension

Rear suspension features a conventional twin shock absorber arrangement giving a full 100mm of movement, and a fat rear tyre delivers high levels of traction and also helps smooth out your ride.

As you would expect on a machine of this type, both wheels are spoked, with a 80/100-18 tyre fitted to the front and a 130/90-15 tyre at the back.

Teardrop fuel tank

Bodywork is pure Drag Star and features a teardrop fuel tank complemented by a flared front fender and deeply valanced rear fender — both of them manufactured from lightweight resin.

Instrumentation is mounted on top of the fuel tank in the traditional cruiser style, and the wide pull-back bars and chromed circular headlight shell complete the picture.

Ultra-low seat height

At only 665mm off the ground the rider’s seat should allow even the smallest of riders to get their feet down in stationary or slow-moving traffic, and its extra-thick padding and contoured profile are sure to make this one of the most luxurious bikes in the category!

Relaxed riding position

And with its forward-mounted footrests and raised, pull-back handlebars, the Drag Star 125 offers one of the most relaxed riding positions to be found on any motorcycle.

Mounted on top of the wide and deep rear fender, the thick pillion pad is designed to ensure that the passenger also travels in comfort.
