Ignition Condenser | Honda CB175 / CB200
A worn ignition condenser is one of the most common reasons a CB175 or CB200 won't rev cleanly. The condenser has no moving parts, but it still degrades with age — and when it does, your points burn and the engine sputters as the revs climb. This is the direct replacement for the CB175 and CB200 family.
Why You Need This
The condenser works with the points to fire the coil. It keeps the points from burning up, and it keeps the coil charged hard enough to make a strong spark as the revs climb. When the condenser weakens you get burnt, pitted points and a top end that sputters, misses, or falls flat as you accelerate past about 5,000 rpm.
The CB175, CL175, SL175, CB200, and CL200 all run a single ignition coil and a single set of points — the 360-degree crank fires both plugs together every revolution. (That's different from the 350/360 twins, which use two separate sets of points.) This condenser is the right one for that single-points system.

Note: The condenser grounds through its mounting tab — clean the surface where it bolts on so it has a solid ground, or it won't do its job.
Installation & Diagnosis
Difficulty: Intermediate
Replace the condenser whenever you replace your points — they're a matched wear pair, and fresh points behind a tired condenser won't last.
To check a suspect condenser, pull the points cover and watch the contacts in a dark spot. A bright spark or arc jumping across the points every time they open points to a bad condenser; a small spark every few seconds is normal. If a previous owner rewired the bike, double-check that the coil wiring is routed correctly while you're in there.

Frequently Asked Questions
How do I know if my condenser is bad?
Burnt or pitted points and a top end that sputters or won't pull past about 5,000 rpm are the classic signs. To confirm, watch the points open in a dark spot — a bright arc across the contacts each time they open means the condenser isn't doing its job. Replace it along with the points.
Does the CB175 / CB200 use one coil or two?
One. The CB175, CL175, SL175, CB200, and CL200 use a single coil and a single set of points, firing both cylinders together. The bigger 350/360 twins use two separate sets of points — so the dual-point diagnostics you'll see for those bikes don't apply here.
Should I replace the points at the same time?
Yes. The condenser and points wear together, so it's worth doing both at once. You'll want our CB175 / CB200 ignition points — there are two plate styles (Nippon-Denso and Hitachi), so match the one already on your bike.
Can I get rid of the points and condenser altogether?
Yes — our Shockwave electronic ignition replaces the points and condenser with a sealed electronic trigger, so there's nothing left to burn out or re-gap.
