Larger displacement and more luxurious equipment!

Equipped with 250cc 4V liquid engine, with a maximum horsepower of 18.4kw, coupled with the balancing shaft which reduces vibrations. Its blue-light digital speedometer contains gear-shifting display, making it easier to select the correct gear.

The design for the front and rear discs greatly improves braking performance, with a 4-way adjustable brake lever, which satisfies demands for all riding styles.



The single sylinder, liquid cooled, fueled by injection, six speed 249.4 c.c. engine delivers 26 bhp/7500 rpm and 2.1 kgm/6500 rpm (15.2 lbs ft/6500 rpm) torque, claimed figures.

Actually a minimum of 3000 rpm is required depending on the selected gear to obtain surge-free acceleration. Engine response is linear and punchy from 5000 rpm upwards. The rev limiter intervenes at 9200 rpm. The speed of 120 km/h (75 mph) is reached comfortably, the top speed of nearly 150 km/h (93 mph) is influenced considerably by road inclination and adverse wind. The operation of the gearbox is really good.

Riding position:

The height of the saddle is low, 790 mm (31.1 in), providing confidence to low stature riders. The pillion is seated quite higher than the rider, the space on the saddle provided is small and hard, which reminds slightly of a supersport 600 c.c. bike and thatís not an advantage! Rider is placed in and over the bike, riding position tends to be neutral: it is comfortable, helping to be alert at the same time. Thus riderís torso is slightly inclined to the front while the handlebar is high and relatively wide.



On the road: Suspensions are soft. A 37 mm fork is equipped at the front, there is no linkage provided for the shock. OE tires are Maxxis promaxx street with dimensions 110/70-17 at the front and 140/70-17 at the rear.

In-town rides the Wolf is greatly neutral, providing easy, unbiased, yet very effective and comfortable rides. It will not impose any restrictions on the rider. The Wolf gives priority to everyday use, boasting unquestioning urban rides. The riding and the feel of the bike on the road reminds of bigger bikes, favouring robustness for agility.

On B-roads the robustness and the stability of the bike are the key riding features, agility comes second. Itís a sure footed bike on the road, providing confidence to the rider which is a feature again that could belong to a bigger bike. Riding is satisfying to the so-called average rider, or on everyday rides.

On the highway the Wolf will be a satisfying bike up to the speed of 120 km/h (75 miles). At a higher speed though, especially in case of windy conditions, some minor weave may be noticed e.g. at 140 km/h (87 mph). Air protection is typical by naked bikes standards.

A 288 mm disc together with a four piston radial caliper and steel braided line are provided at the front. A 222 mm disc together with a single piston caliper is provided at the rear. Brakes are linear and powerful, providing relatively good feedback. In case of powerful braking, the diving of the front end is considerable, due to the soft fork.

Build quality and the plastic parts assembly are indicative for the Sym factory, that means superb.

The Wolf is an alternative to modern sporty rivals, which clearly gives priority to everyday riding. Therefore it looks like and it is called a Wolf, although the friendliness and the effectiveness provided belong to a Labrador!
