Front Chain Sprocket | Honda CB350 / CB360 / CB450 / CB500T
The front sprocket is made of harder steel than the rear, but it is the smaller of the two and spins faster — which is why it is usually the first part of the drivetrain to wear out. This is an exact replacement for the factory front drive sprocket on Honda CB350 / CL350, CB360 / CL360 / CJ360, CB450 / CL450, and CB500T motorcycles, made from high quality steel in the factory 530 chain pitch.
Why You Need This
Chains and sprockets are an ongoing wear item on these bikes, and how well the previous owners kept up with chain adjustments and lubrication decides how much life is left in yours. When the teeth go thin and pointy, the sprocket is done — and running a worn front sprocket will accelerate wear on a new chain.
Pick the factory tooth count to keep the stock final-drive ratio, or change the count to fit your riding style: fewer teeth on the front gives greater acceleration off the line at the cost of top end, while more teeth gives better top end with reduced acceleration. Changing the front sprocket is the fastest and cheapest way to change how the bike feels to ride.
One Honda trick worth knowing before you buy: depending on how the teeth have worn, the front sprocket can sometimes be flipped over to get a little more service life out of it. If the teeth are already thin or pointed on both faces, replace it.

Note: A new drive chain cut to the proper link count must be installed when changing to a different sprocket size — the chain length changes with the tooth count.

Model-Specific Notes
Installation
Difficulty: Intermediate
When you install a new front sprocket, it is also a good idea to replace the rear sprocket and fit a new drive chain at the same time — a fresh part running against worn ones wears out early. If you changed tooth counts, count your chain length against the new combination rather than assuming the factory number.
Use a high quality chain lube on the new chain and sprockets rather than gear oil, and keep the chain adjusted — chain care is what preserves sprocket life.
Our Sprockets 101 video covers how sprockets wear, how front and rear tooth counts change the final-drive ratio, and how to figure the chain length you need after a swap.
Frequently Asked Questions
Which tooth count should I pick?
The factory size is 16 tooth for the CB350, CL350, CB360, CL360, and CJ360, and 15 tooth for the CB450, CL450, and CB500T. Stick with the factory count to keep stock gearing. Go up a tooth for more relaxed highway cruising, or down a tooth for stronger acceleration — and plan on a new chain in the matching length either way.
Will this fit my SL350?
Not the SL350 K1 or K2 — those use a 520-pitch drivetrain, so this 530-pitch sprocket does not interchange. The SL350 K1 & K2 Front Sprocket is the correct part for them.
Do I need a new chain when I change tooth counts?
Yes. The link count changes with the sprocket combination. For reference, the factory chain lengths are: CB350 = 94 links, CL350 = 96, CB360 / CL360 = 94, CJ360 = 98, CB450 / CL450 = 92, CB500T = 96. Our 530 roller drive chain is cut to your specified link count before shipping.
How do I know my front sprocket is worn?
Look at the teeth: thin, pointed teeth mean the sprocket is done. The front wears before the rear because it is smaller and turns faster for the same road speed. Depending on the wear pattern, a Honda front sprocket can sometimes be flipped to buy a little more life, but worn is worn — replace it before it ruins a new chain.
Does this fit the CB500K, CB550, or CB750?
No. The CB500K, CB550, and CB750 use a different front sprocket — see our CB500K / CB550 / CB750 Front Sprocket.
