YZ125 2016
Updated 2 November 2026
The fun one. A 2016 YZ125, two-stroke, bought as a race-pack bike so it came with the oversized front disc and the good bits already on it. Pipe's a DEP, suspension's been through a tuner and set up soft for sand and natural terrain, and that's about where the modifying stopped because it didn't need any more. It's the bike I ride when I want to ride, not when I want to work. Nothing on the list right now except a brake flush it's owed and a rear pedal that sits a touch low.
Where it sits
- Fork
- 12 out compression, 14 out rebound
- Shock
- 16 out low speed, 1.5 turns out high speed, 16 out rebound
- Sag
- 108mm cold on the shop ticket. Not read with me on it yet.
- Springs
- Standard, kept at the service
- Gearing
- 50T rear, up from the 49T it came with
- Hours
- Meter fitted July 2026 at zero on the refreshed bike
What's been done
- Sep 2026 Suspension back in. Three days at Reds, nothing to chase. Signed off.
- Aug 2026 Forks and shock serviced and revalved, new seals. No new springs needed.
- Jul 2026 Forks and shock out for the tuner. Linkage, swingarm and steering head greased. New grips. New chain, 50T rear, hour meter on.
- 2016 Bought new with the race pack. GYTR bits, V-Force 4 reeds, oversized front disc, 49T rear, DEP pipe. Ten weekends that year, then mostly shed.
Owed
- Brake fluid flush both ends, then decide if the front needs more than that
- Rear brake pedal up a touch, it sits below the peg
- Read the sag with someone holding the bike
- Clean up the linkage bolt that came out part-seized
