Polini XP4 Street 50cc Bike Review
Reviews brought to you by Super Pocket Bikes
The first company to manufacture engines specially designed for pocket bikes, Polini-Motori produce one of the most popular pocket bike lines, the Dreambike 910 Series.
Now from Polini Uk comes the first 50cc pit bike. The XP4 is street legal and fun on designated circuits. The engine capacity has been kept at 50cc to allow it to be ridden by 14 year olds in most countries. Great care has been used in the details of this superb bike as we have come to expect from Polini.
The XP4 has a 4-stroke engine, four speed transmission and manual clutch. High performance engine kits are available to mod this bike for greater performance. The frame has been optimised for better weight distribution to give better handling and stability especially on uneven ground. The suspension has been developed from the racing success of Polini’s X3 2-stroke engines and is the best available for a 4-stroke pit bike. the heavy duty suspension is designed specifically for adult riders. an upgrade kit is also available.
Mechanical disc brakes make maintenance easy although for those who prefer hydraulic brakes an upgrade kit is available. The handlebars are made from heavy-duty alloy and are designed for adult riders. Non slip pads on the ends of the handlebars and footrests give good protection against falling or sliding on hard surfaces. The hydraulic fork has 33mm fork tubes fitted with heavy-duty springs suitable for adult riders. Stability when motocross riding is assured by the cylindrical roller bearings supporting the steering tube
The handmade exhaust system and silencer are manufactured from light alloy to optimise the best horsepower gains while keeping the noise level low.
The steel rims are a bit of a let down after the excellent attention to detail of the rest of the bike. Upgrade with the available aluminium rims to give a much better look to your bike!
