2011 BETA Minitrial Review


Built for children between the ages of six and nine years, the 2011 BETA Minitrial has a single-cylinder engine with a single trial seat. It has driver-only foot pegs, and the engine displacement to weight ratio is 0.53cc. The two-stroke engine has a displacement of 49cc, and the bike has a kick starting mechanism. For a bike of its size, the Minitrail has remarkably powerful performance. It is quick to get up to speed and handles very well on offroad trails. Fuel capacity is expectedly low, so the bike requires refueling a lot of times with a gas/oil premix fuel. However, it is not meant for long-distance travel, so the small fuel tank should not be an issue. The bike, which is manufactured in Italy, comes with a six-month warranty that protects against major defects in workmanship and manufacturing. Overall, the 2011 BETA Minitrial makes a great choice for young riders who are looking to start a new hobby on the Motocross trail.
