aprilia rx 125 tuning: more pull without making the bike unreliable
I am opening a proper aprilia rx 125 tuning thread because most advice I find is either "put an exhaust on it" or "just buy a bigger bike", which is not very helpful when you actually own an RX 125, ride it every day, and still need it to start on Monday morning.
My goal with aprilia rx 125 tuning is not to make impossible horsepower. I want better pull out of slow corners, cleaner response on hills, sensible gearing for mixed road and light trail riding, and no reliability drama. I would also like to understand what has to be checked before tuning: chain and sprockets, valve clearance, air filter, spark plug, ECU faults, exhaust leaks, throttle body or carb setup depending on version, and whether the bike is already healthy.
