Short answer: at current catalog prices, the CFMOTO 450SR is cheaper to refresh at the front and the tank, while the ZXMOTO 500RR costs more on its tank cover but offers a complete, lower-cost tail. A screen-plus-tank order comes to about $498 for the 450SR and $598 for the 500RR. Add the 500RR seat cowl and you are at $797.
That gap matters when you are pricing a cosmetic refresh after a drop, or deciding which bike is cheaper to keep looking sharp. This guide compares the bodywork both bikes actually have in the ISLEPARTS catalog, with fitment notes and the order we would place first.
Two different platforms, two separate parts lists
The CFMOTO 450SR uses a 449.5 cc liquid-cooled inline-twin. In the US the same bike is sold as the 450SS, so search both names before you order. The ZXMOTO 500RR is a different machine: an inline-four in the roughly 470 cc class, also listed as ZX 500RR or ZX-500RR. It is not a Kawasaki ZX-series bike, and parts do not cross over.
Because the two bikes share no body panels, every comparison below is about price and coverage, not compatibility. For a model-by-model list, see the 450SR parts guide and the 500RR parts guide.
Bodywork prices, side by side
These are the bodywork items each bike currently lists. Prices are USD catalog prices and do not include shipping or duties.
- Front screen: 450SR Racing Modified Windshield $199; 450SR V3 Front Windshield $239–$299 across 15 color-and-tint combinations; 500RR Tall Windshield $199 in three tints.
- Tank cover: 450SR Half-Wrap Tank Cover $299 in three colors; 500RR Tank Cover $399 in five colors.
- Tail: 500RR Seat Cowl $199 in four colors and 500RR Short Tail $99. The 450SR list currently has no seat cowl or short tail.
- Side aero: 450SR V4 Winglet $299 and Concept Winglet $199; 500RR Shark Fin Side Panel $399 in three colors.
- Cockpit bodywork: 450SR Top Triple Clamp + Clip-On Handlebars $399. No equivalent 500RR item is listed.
Where the 450SR is the cheaper build
The 450SR wins on the parts most riders replace first. Its half-wrap tank cover is $100 less than the 500RR item, and its V3 screen starts at $239 with 15 combinations, so you can match body color and tint without paying a premium. Winglets start at $199, and a full cockpit change with the triple clamp and clip-ons is $399.
For a front-and-tank refresh, the 450SR is the lower bill: $199 for the Racing Modified screen or $239 for the V3, plus $299 for the tank cover.
Where the 500RR earns its higher ticket
The 500RR tank cover is $399, but it comes in five finishes including fluorescent green, fluorescent pink and lava red, which is a wider palette than the 450SR's silver, gloss white and matte black. The tail is where the 500RR pulls ahead: a $199 seat cowl and a $99 short tail give you a complete rear-end change that the 450SR catalog does not currently offer.
If your goal is a race-style rear end, the 500RR is the only one of the two with an off-the-shelf answer, and $298 for cowl plus short tail is still less than a single $399 shark fin panel.
What to order first
- Screen first. It changes wind protection and is the most visible upgrade. Both bikes start at $199.
- Tank cover second. It takes the most wear from knees and bags, and it is the panel most likely to look tired. Budget $299 on the 450SR, $399 on the 500RR.
- Tail third, if you want the look. Only the 500RR has a seat cowl and short tail in the current list.
- Aero and cockpit last. Winglets and clip-ons change the bike's silhouette, but they are the easiest place to overspend before fitment is confirmed.
Before ordering any panel, confirm the model year and the market name. US bikes are sold as the 450SS and 675SS, so a part listed for the 450SR is usually the right one, but year-to-year bodywork changes are common. Browse the 450SR / 450SS collection and the 500RR collection to check what is currently in stock.
Budget for shipping and variant prices
Catalog prices are only part of the bill. These parts ship from the China partner factory, with free shipping advertised and duties extra, so a $299 tank cover is not the landed cost. Variant prices also differ: the 450SR V3 screen runs $239–$299 depending on body color and tint, while the 675SR-R split screen runs $269–$329. Check the exact variant before you compare totals.
Frequently asked questions
Are 450SR and 500RR bodywork parts interchangeable?
No. They are different platforms with different mounting points. Nothing in this comparison is a cross-fit recommendation.
Why is the 500RR tank cover $100 more?
The catalog price is $399 versus $299. The 500RR part is offered in five finishes, and the price reflects that part and finish range, not a fitment advantage.
Can I price a full refresh from these numbers?
Yes, as a starting budget: about $498 for a 450SR screen and tank cover, or $598 for the 500RR equivalents, rising to $797 with the seat cowl. Add shipping and any duties, and confirm the exact variant price before checkout.
