Hello everyone
Facing a problem it seems the pickup in 1st gear is less bike didnt accelerate that much but in 2nd and 3rd gear it pulls great is this a problem or it's normal in 650cc bike
That is typical in some of the most powerful Japanese motorcycles. Apparently the manufacturers (or their lawyers) are worried about riders spinning their rear wheels and loosing control when using full throttle in first gear. To address this potential issue their FI computers cut power when the bikes are in the lower gears. However, the European manufacturers don't seem to offer such a "feature" as they use traction control systems to keep things from getting out of control when the throttle is whacked open in low gear.
Or they might be cutting power to comply with some sort of noise regulation.
In any case, I am having trouble imagining that Royal Enfield would be worried about putting too much power to the ground in first gear or making excessive noise. However, it is possible that the company that they used to design their fuel injection system was using a standard Japanese program that automatically cut power in first gear - just because.
Or it could be that there is actually some sort of issue with your particular bike. You will have to ask other owners of the 650 and see if they are having a similar experience.
