 bolt
Thread diameter in mm refers to “male” thread and is measured on the outer surface (peak, not trough)
of the bolt thread (equals diameter of smooth portion of bolt shaft if not completely cut with threads).
UBS: “Uniform Bearing Stress”. UBS bolts are designed to resist loosening.
U-nut: self-locking nut
Thread Locking Agent
ALOC - bolts have a pre-applied locking agent on them.
According to the service manual, when applying a thread locking agent to specific bolts, use a small
amount towards the end of the bolt, skipping the first 1 to 3 mm. The width of the application area
should be 5.5 to 7.5 mm wide. Otherwise just apply a small amount of locking agent to the end of the
bolt threads resulting in the locking agent being distributed throughout. Threads should be clean, dry
and oil-free before applying thread locking agent. Avoid contact with plastic.
Use a medium strength locking agent unless otherwise specified.

Oil and Oil Filter Change
The oil and filter change procedure for the CBR250RA is documented on this website.
Recommended Engine Oil
Pro Honda GN4 4-stroke oil or equivalent motor oil.
API service specification: SG or higher
JASO T 903 standard: MA
Viscosity: 10W-30 (10W-40 also acceptable)
Engine Oil Capacity
1.4 liters (1.5 US qt) – oil change only
1.5 liters (1.6 US qt) – oil and filter change
Oil Level Check
With the motorcycle resting on the side stand on level ground, start the engine and let it idle for about 3
minutes and then turn it off. Wait for 2 to 3 minutes. With the bike held upright (vertical) on level
(horizontal) ground, check the oil sight glass (inspection window). The oil level should be between the
upper and lower marks.
If the oil level is below or near the lower mark, remove the oil filler cap and add oil up to the upper oil
level mark. Do not overfill. Inspect the oil filler cap O-ring, and replace it if not in good condition. Apply
engine oil to the O-ring. Reinstall the oil filler cap.
Spark Plug
This motorcycle uses a spark plug with an iridium center electrode. Do not adjust the spark plug gap.
Spark plug: NGK SIMR8A9
Spark plug gap: 0.80 – 0.90 mm (0.031 – 0.035 in). Replace sparkplug if gap greater than or equal to 1.0
mm (0.04 in).
Valve Clearance
Measure with the engine cold: below 35C (95F)
Intake: 0.16 +/- 0.03 mm (0.006 +/- 0.001 in)
Exhaust: 0.27 +/- 0.03 mm (0.011 +/- 0.001 in)
Valve Clearance Inspection
The valve clearance inspection procedure for the CBR250RA is documented on this website.
Valve Clearance Adjustment
The valve clearance adjustment procedure for the CBR250RA is documented on this website.

2011 – 2012 Honda CBR250R/RA Service Info. Last updated June 4, 2025.
Engine Idle Speed
1400 +/- 100 rpm
Coolant (Antifreeze)
Recommended Coolant: Pro Honda HP Coolant or an equivalent high quality ethylene glycol antifreeze
containing silicate-free corrosion inhibitors, premixed or a 1:1 ratio of concentrated antifreeze and
distilled water.
Coolant capacity – radiator and engine: 1.1 liters (1.16 US qt)
Coolant capacity – at draining: 0.79 liters (0.83 US qt)
Coolant capacity – reserve tank: 0.25 liters (0.26 US qt)
Drive Chain
Chain slack: 20 – 30 mm (0.8 – 1.2 in),
with the motorcycle on the side stand and the transmission in neutral, measured midway between the
sprockets, on the lower chain run. Generally, chain slack (vertical movement) is measured at the tightest
point of the chain, as chains typically wear unevenly.
This motorcycle comes with an O-ring type chain.
Standard number of chain links: 108
Replacement chain: DID520VF or RK520KLO
Brake Fluid
Type: DOT 3 or DOT 4 from a sealed container
