Field repair

Fuse box
40 A main fuse behind the right steering-head cover; accessory fuse block beneath the rider seat.
Battery access
Remove the skid plate; disconnect negative first, then positive.

Plug and reinflate a tubeless tread puncture

  1. 01Confirm the damage is confined to the tread and the bead, sidewall and carcass are intact; otherwise recover the motorcycle.
  2. 02Remove the object, prepare the puncture and install a repair string with the insertion tool.
  3. 03Inflate gradually, leak-check the repair and set the tyre to the documented cold pressure with any temperature correction applied.
  4. 04Ride conservatively and replace or professionally repair the tyre as soon as practical.

Replace a failed fuse

  1. 01Switch the motorcycle off and locate the fuse block.
  2. 02Remove the right steering-head cover for the main fuse or the rider seat for the accessory fuse block.
  3. 03Replace only the failed fuse with the same type and rating; never bridge or uprate it.
  4. 04Refit all covers. If the replacement fails again, stop and diagnose the circuit or recover the motorcycle.

Check and top up coolant safely

  1. 01Park on level ground on the jiffy stand, switch off and allow the engine and cooling system to become completely cold.
  2. 02Inspect for leaks before removing the coolant reservoir plug or dipstick; never open a hot, pressurised cooling system.
  3. 03Top only with the documented coolant to the MAX mark and refit the plug or dipstick.
  4. 04If the reservoir was empty, the level falls again or overheating continues, stop and recover the motorcycle because the system may require repair and air purging.

Inspect, clean and lubricate the drive chain

  1. 01Secure the unloaded motorcycle and find the tightest part of the chain.
  2. 02Measure vertical deflection midway between the sprockets: the 2025 RA1250ST owner manual specifies 50–60 mm on the centre stand or 46–56 mm on the jiffy stand.
  3. 03Inspect the 525 chain, master link, sprocket teeth and chain guide; clean with chain-safe cleaner and lubricate after riding while warm.
  4. 04Do not continue if the chain has tight links, damaged rollers, an insecure master link or hooked or broken sprocket teeth; use the exact owner-manual adjustment procedure.
