“In a comparison video, the 2EXTREME 70ccm cylinder was tested against the much more expensive Stage 6 Streetrace 70ccm. A commenter on the video who has used both the 50cc and 70cc versions of the 2EXTREME cylinder reported having no problems and stated they are significantly better than original cylinders. One 70cc cylinder on a Minarelli engine had run for nearly 18,000 km.”

“This video provides a detailed look at the 2EXTREME Sport 70ccm tuning cylinder for Minarelli LC engines, describing it as a durable and suitable for everyday use. The reviewer tested the cylinder on a dynamometer and, with specific components like a Yasuni R exhaust and a 17.5mm carburetor, achieved approximately 10 horsepower. The review offers installation tips and emphasizes the product's longevity if properly set up.”

“In a test bench comparison against the Top Performance Trophy 70cc, the 2EXTREME 70cc cylinder performed surprisingly well, achieving 8.8 PS. The reviewer notes the significant price difference, with the 2EXTREME cylinder being much cheaper. While the Top Performance cylinder is praised for its clean finish and included accessories, the 2EXTREME is highlighted for its impressive performance for the price.”

“A livestream video showcases the 2EXTREME Sport 70ccm Minarelli cylinder achieving 10.2 PS with a relatively simple setup costing around 99 euros (excluding the exhaust). The setup included a 17.5mm 2EXTREME carburetor and carbon membrane plates. The host expresses excitement over reaching this performance figure.”

“This review describes the 2EXTREME 70cc cylinder as a very affordable option with high power, quality, and durability, calling its price-to-performance ratio almost unbeatable. With a standard crankshaft and a 17.5mm carburetor, a performance of 8.5 to 9 PS can be expected. By using a Yasuni C16 exhaust, the performance can be boosted to 10.5 PS without modifying the cylinder itself.”
