Profender Suspension Setup

Set up your Profender shock correctly the first time — no guesswork. Enter your weight and pick your bike. The app gives you every number you need: preload in millimetres, compression in clicks, rebound in clicks, whether to run the SOFT or FIRM spring, and the exact spring part number for your bike. Every value comes straight from the Profender factory charts — the same charts printed on the manual inside the box. Nothing is estimated or copied second-hand. WHAT IT DOES • Pick your series and model, get your settings instantly • Adjusts for real load — rider, pillion and luggage • Choose street use or heavy duty (loaded / high speed) • Shows the spring part number so you can order the right one • Open the full factory chart, zoom and swipe through it • Save several bikes and switch between them without losing your settings • Thai / English · dark and light mode • Free, no ads SUPPORTS 8 PROFENDER SERIES SERIES X+ · AIR+ · FLASH+ · TYPE 4 · XS · AIR · FLASH · MAX Not every series adjusts the same way, so the app only shows the knobs your shock actually has — a rebound-only series will not show a compression field you cannot turn. OVER 60 MODELS CHARTED Honda · Yamaha · Vespa · Zontes · Lambretta · Aprilia Automatics, underbones, European scooters and maxi scooters. New models are added over the air — no app update needed. WHO IT IS FOR • Riders who just fitted a Profender shock and want it set up right • Shops fitting shocks for customers — pull the numbers up at the counter • Anyone whose load changes often, riding solo one day and two-up the next • Anyone who lost the manual that came in the box ABOUT PROFENDER PROFENDER CO., LTD. — a Thai shock absorber manufacturer exporting worldwide. Contact details are built into the app: LINE, Facebook, Instagram, YouTube, phone numbers and shop address. Note: this app is a setup reference. Nothing is sold inside the app.
