Yoshimura - RS-4 Signature Series Full System (Suzuki)

Built straight from Yoshimura’s racing pedigree, the RS-4 Signature Series Full System gives Suzuki riders that factory-level performance, sound, and style. Designed to pull harder out of the gate and add torque throughout the rev range, the RS-4 helps your RM-Z450 launch strong, hook up clean, and pull longer down the straight. It’s a complete system engineered to win — lighter than stock, smoother through the midrange, and tuned for that deep Yoshimura growl that makes a four-stroke sound just right.

The RS-4’s pentagonal canister isn’t just for looks — it houses Yoshimura’s Polyresonant Duplex Chamber and stepped baffle design to control noise while boosting power. A stainless steel header and carbon fiber end cap give it a clean factory finish that can take real abuse. And if you want to cut even more weight, Yoshimura offers titanium versions that look as good as they perform.

Why We Like It:
You can feel the race DNA in this system. Throttle response snaps to life, the midrange torque feels meatier, and it still keeps sound levels smart and clean. The RS-4 gives your Suzuki that pro-level punch without making it harsh or high-maintenance — just smooth, reliable power that hits right when you need it.

Why It’ll Work for You:
This system transforms how your bike builds power — smoother off the bottom, stronger through the mid, and more drive when you twist it wide open. The Polyresonant Chamber controls sound without killing flow, while the stepped baffle helps your RM-Z pull harder through every gear. It’s a true race-bred setup that delivers consistent performance, lighter weight, and that unmistakable Yoshimura tone — refined, powerful, and ready for the gate.

The Caddy fulfills it's duty
Color: Black, Size: Medium
This caddy turns out to be everything I hoped it would. So often I'll purchase an item and it turns out to be cheaply made or wonky. But this 2-Tier Kitchen Sink Caddy fulfilled it's mission and cleaned up my sink area. Everything is handily stored in it's compartments.

Be careful of sharp edges
Color: Silver, Size: Medium, Color: Silver, Size: Medium
This is a decent organizer for the kitchen. Not too big and not too small for what I have. I like how it has two tiers so I can put soap bottles on top and sponges underneath. I also like that it just stands on the rounded edges instead of having legs. Those can start looking a little gross over time. I’m not sure if it’s just the one I bought, but you do want to be careful. Some of the welded parts had metal sticking up that I had to hammer down. The drain plate has some sharp edges. Not as sharp as a knife, but sharp enough you might cut yourself. I have another one from a different seller and just one tier, but it has a similar drain plate. That one has slightly rounded edges compared to this one. I would have like it more if the top basket was slightly taller. I get scared the glass soap dispensers I have might get knocked over easily. It would also be nice if the bottom could have a bit weight to it to avoid tipping. Overall, I would still recommend this over a single basket if you have more items you want to hold.
