When your motorcycle or scooter's final or primary drive needs a new sprocket, the choice comes down to more than just tooth count. You want a part that matches your application without turning the replacement into a guessing game. This guide looks at one specific option: the NEW TSUBAKI POWER TRANSMISSION COMPONENTS H40B24F-7/8 SPROCKET, listed at USD 24.99.
Quick verdict
If you need a new sprocket and the H40B24F-7/8 configuration fits your setup, this Tsubaki part is a straightforward choice. It is listed as new, comes from Japan according to the product attributes, and carries the Tsubaki name in the title. At USD 24.99, it's a specific replacement part that you buy with a clear purpose rather than a generic accessory.
Who it suits
This sprocket suits someone working on a motorcycle or scooter drivetrain-specifically the final or primary drive system, as the product description mentions. If you already know your vehicle uses this Tsubaki part number or an equivalent size, this listing gives you a new component from a recognizable manufacturer in the power transmission space. It also fits a shopper who prefers a Japanese-origin part, since the attributes list Japan as the country of origin.
What stands out from the listed details
The product title makes the core identity clear: it is a new Tsubaki power transmission component, model H40B24F, with a 7/8-inch bore size indicated by the suffix. The description reinforces that it is designed for motorcycle and scooter parts, specifically for the transmission and drivetrain system. The manufacturer part number H40B24F 7/8 gives you a concrete reference to cross-check against your vehicle's requirements.
Another notable detail is the condition-new. That removes the uncertainty of used sprockets, where wear on the teeth or splines is hard to judge from a photo. The Japan country of origin is also a useful reference point for buyers who consider origin in their purchasing decision. From a value perspective, the USD 24.99 price puts it in a specific mid-range position for a single sprocket replacement, though the price alone doesn't tell you if it's the right fit for your bike.
Meaningful trade-offs
The main trade-off is that the listing only provides the basic details: part number, bore size indication, condition, origin, and intended application. You won't find a detailed breakdown of material hardness, tooth profile, or exact compatibility list in the supplied information. That means you need to be confident that the H40B24F-7/8 designation matches your scooter or motorcycle before ordering. The description mentions final and primary drive, but that's a broad category-it's on you to verify this specific part fits your vehicle's existing chain pitch, width, and bolt pattern.
Another consideration is that this is a single sprocket, not a complete kit. There's no chain or companion sprocket included in the listing, so plan for the rest of your drivetrain parts separately. Also, while the Tsubaki name is prominent, the specific performance characteristics like wear life or load capacity are not stated in the product information. You're buying based on the brand and part number, not on a stated performance metric.
Bottom line
For a shopper who has already identified the H40B24F-7/8 as the right replacement part, this listing offers a new Tsubaki-branded sprocket, from Japan, at USD 24.99. It's a focused purchase for a known replacement job. If you're still in the research phase, use the part number to confirm fitment before committing. If the numbers align, this is a reasonable, purpose-built choice for your drivetrain.
NEW TSUBAKI POWER TRANSMISSION COMPONENTS H40B24F-7/8 SPROCKET
This is the exact product in this guide. The listing describes it as a new motorcycle and scooter sprocket meant for the transmission and drivetrain, with a 7/8 bore designation in the title. At USD 24.99, it's a part-specific purchase rather than a universal upgrade. The clear manufacturer part number is the strongest asset here, since it gives you a concrete reference to verify before you buy. The limitation is that the supplied details don't go deeper into material specs or exact vehicle compatibility, so you need to rely on your own fitment research. If you've already done that, this is a simple, direct transaction.
