What are the pros and cons of upgrading from 125cc to 150cc cylinder kits?

125 motorcycle upgraded to 150 motorcycle cylinder kit has the advantage of being more powerful during driving. The disadvantage is that if blindly replaced, subsequent problems are likely to occur. The following is a detailed introduction about motorcycles: Overview: Motorcycles, driven by gasoline engines, are two-wheeled or three-wheeled vehicles that rely on handlebars to steer the front wheel. Light and flexible, fast driving, widely used for patrol, passenger and cargo transportation, etc., and also used as sports equipment. Composition: Motorcycles are composed of five parts: engine, transmission system, walking system, steering, braking system and electrical instrument equipment. The engine is a two-stroke or four-stroke gasoline engine, using air-cooled cooling, with natural air-cooled and forced air-cooled two types. The engine crankcase is integrated with the clutch and gearbox, and the structure is compact.
As a motorcycle enthusiast who frequently tinkers with bikes, I must say upgrading from 125cc to 150cc cylinder kits does improve power output, especially noticeable low-end torque enhancement that makes hill climbing and overtaking much easier. However, be aware that post-modification fuel consumption increases by about 10%, engine vibration becomes more pronounced, and the stock cooling system may struggle with sustained high RPMs. Most crucially is the legality issue - the modified displacement will fail annual vehicle inspections, and you risk fines during traffic stops, so carefully weigh these risks before proceeding. Additionally, you'll need matching carburetor and exhaust modifications, otherwise power could actually decrease. Last time I did this conversion, I even encountered hard-starting issues that took considerable effort to properly tune.
