front or rear for Vespa ACMA GL up to 150 km/h profile: classic 9″ ECE-R75 Tyre Classic and for tuned engines Product description The Classic 9″ tyres for the Vespa ACMA GL. The only tyres in 3.50-9″, even with a speed index of 150 km/h. Tyres for Vespa’s ACMA GL (“Grand Luxe”), manufactured under licence by Piaggio in France from 1956 to 1958, were hard to find for decades as they require the exotic 3.50-9 size. Scootershop has launched a new production with its own mould to remedy this shortage on the market. Speed index “P”, up to 150 Km/h Classic tread Good properties on dry and wet surfaces Also suitable for “tubeless” rims With a speed index and approval for up to 150 km/h, the Classic tyre allows much more than a Vespa can ride. Nevertheless, it’s good to know that you don’t have to worry about tyres if you own a Vespa ACMA GL. The classic tread in combination with the rubber compound make this tyre the ideal companion, not only on dry roads, but also on wet road
