Unmistakable elegance in size and elegant in its lines, the new Liberty 3V takes the baton from a model that distinguished itself for its sober & refined design. The new Piaggio medium engine capacity high wheeler the salient features which have always distinguished Liberty, lượt thích the front headlamp, kindly triangular, & the “tie”, in other words the of the centre leg guard in relief that goes from the handlebar down almost lớn the mudguard, by now an elegant distinguishing feature of the latest generation of Piaggio The chromed inserts enhance the finishes: the elegant embellishment on which the Piaggio logo is set, the profiles of the turn indicators with transparent, the handle of the glove door and the fork stanchion guards. The easy to read instruments, including clock with date, speedometer, mileage & fuel màn chơi indicator all together with far more modern graphics. The abundance of service LEDs is with the theft immobilizer, a standard feature on Liberty 3V. Besides the chromed parts, the new look of Piaggio Liberty 3V is further enhanced by details that denote the care taken such as, for example, the rear painted handle, the luggage rack for mounting the top box và the practical pull-out passenger footboards.


Even more room và

On the new Liberty 3V the already riding và load capacity have been further improved by paying particular attention to the saddle surface & the under it. The saddle is new with a more tapered shape along the sides so it is easier for everyone, whatever their stature, khổng lồ put both feet on the ground; for the padding – both for the rider and the person riding pillion – a more foamed sản phẩm is used, upholstered with a strong slip-proof fabric. The loading capacity of the helmet has been increased 23%, going from 8.8 to 10.8 litres: this is because the battery has been moved, now in the legshield back plate box which can still be used lớn put small, everyday things in. Besides the helmet, which can house the demi jet helmet without visor, Piaggio Liberty 3V also has a luggage hook in the leg shield back plate which is extremely useful và practical for carrying other objects, taking advantage of the practical flat footboard.


Renewed chassis

But the vehicle’s main values change due to lớn the new dimensions of the tyres & wheel rims. Liberty 3V is shorter (1,920 milimet against the 1,935 milimet of the previous model), but it has a bigger wheelbase (1,345 mm against the 1,325 mm of the previous model) which increases the feeling of stability và safety at all speeds. The front wheel rim goes from 16 to lớn 15 inches and takes a narrower tyre but with a higher shoulder (80/90 instead of 90/80); the rear one is still 14” và takes a 100/80 tyre (in place of the previous one which was 110/80). This solution is a proper technical choice that aims at improving dynamic performance, increasing manageability and fuel The new dimensions of the rims and tyres mean optimising in absorbing irregularities thanks lớn the front tyre’s higher shoulder. Given the same braking system ( of a front 240 milimet disc on which a double piston calliper works and a rear 140 mm drum) with the new wheel dimensions, braking is even more efficient, effective, reliable and modulable.
