Ikon Rear Shocks | Honda CB175 / CL175 / CB200
Tired rear shocks bounce over every bump and let the back end wallow through corners. Ikon rear shocks are the top of our suspension lineup for the small Honda twins — a rebuildable, fully adjustable upgrade. Sold as a pair.
Why You Need This
Upgrade your vintage Honda’s ride while keeping its classic look. These Ikon shocks have been road-tested for more than 10,000 miles by the CMC crew — whether you’re after comfort, handling, or style, they’re a top pick, and they may be the last set of rear shocks you ever buy for your bike.
Features
- Fully rebuildable — the body, valving, seals, and oil can all be serviced rather than tossed
- Three-position spring preload to set ride height and sag for your weight
- Four-position rebound damping on the Fully Adjustable version — control how fast the shock returns to rest
- Stock-style look, in a black or chrome body
Pick the style that suits your setup: the Fully Adjustable shock adds four-position rebound control on top of the spring preload (black or chrome body), while the Basic Adjustable is built to the same standard with spring preload only.
About Ikon
Ikon Suspension builds these in Australia, and the company traces its roots to the iconic Koni racing shocks. Every Ikon shock is 100% rebuildable, and Common Motor is an authorized Ikon service center — so when they eventually wear, they get rebuilt, not thrown away.

Dimensions
| Measurement | Value |
|---|
| Eyelet to Clevis Eyelet (center-to-center) | 11.75" (298 mm) |
| Upper Eyelet ID | 0.63" (16mm) |
| Upper Eyelet Width | 1.02" (26mm) |
| Clevis Inside Width | 0.8" (19mm) |
| Clevis Bolt Thread | M8 |
These share the 16mm upper eye and M8 clevis with our factory-style CB175 / CB200 shocks. The bigger CB350–CB550 Ikon shocks use a larger M10 clevis — a different lower mount.
Note — chain guard: The Basic Adjustable shocks will not clear the factory chain guard on the CB175 / CL175 / CB200 / CL200 without modifying or removing it. The Fully Adjustable shocks do clear the chain guard — choose those if you want to keep the stock guard as-is.
Installation
Difficulty: Beginner
Tools needed: A wrench for the 8mm lower bolt and the 10mm upper cap nut.
- Bolt the shocks on with the eyelet end up and the clevis end down — an 8mm bolt at the bottom, a 10mm cap nut up top.
- Set the rider sag: with you seated on the bike, the shock should compress about a third of its travel. Adjust the spring preload to get there.
- On the Fully Adjustable version, match the rebound to the spring position: if the spring is on 3, set the rebound to 3 or 4; spring 2, rebound 2–3; and so on.

Frequently Asked Questions
Will the Basic Adjustable shocks clear my chain guard?
No. On the CB175 / CL175 / CB200 / CL200, the Basic Adjustable shocks won’t clear the factory chain guard without modifying or removing it. The Fully Adjustable shocks do clear it — pick those if you want to keep the stock guard.
What’s the difference between the Fully Adjustable and Basic versions?
Both have three-position spring preload and the same build quality. The Fully Adjustable adds four-position rebound damping and clears the stock chain guard; the Basic Adjustable has the preload only and needs the chain guard modified or removed.
Are these rebuildable?
Yes. Every Ikon shock is 100% rebuildable — the body, valving, seals, and oil can all be serviced — and Common Motor is an authorized Ikon service center, so they can be rebuilt rather than replaced when they wear.
Will these fit my SL175?
No — not as a direct fit. The SL175 used a longer rear shock unique to that model: its shock spring is 8.52" long versus 7.41" on the CB / CL175. We do not currently carry a direct-fit SL175 rear shock, so fitting these means deliberately running the rear shorter than stock.
Will these fit my bike?
They fit the CB175 / CL175 (1968–1973), CB200 and CB200T (1973–1976), and CL200 (1974), and they also fit the CD175, CA175, and CB160. They do NOT fit the SL175. For the bigger CB350 / CB360 / CB450 / CB550 twins, see our Ikon CB350–CB550 shocks; for a lower-cost option on these same small twins, the factory-style shocks.
How do I set them up?
Set the spring preload so the shock compresses about a third of its travel with you seated, then match the rebound to the spring position (spring 3 → rebound 3–4, and so on). Tighten the preload for a heavier rider or when carrying a passenger.
