The best pit bike bolt kit depends on which fasteners need replacing: choose a frame-specific set for chassis hardware, a CRF50-style kit for compatible body panels, or a broad assortment for general repairs. The Podoy kit is best for fairings, while the YD-PS001 and Greesp sets target pit bike frames. Tusk offers a motorcycle-focused metric assortment, and smseace provides a large general-purpose selection. Check the original bolt size, thread, length, and mounting location before ordering; engine displacement alone does not confirm fit.

Podoy CRF50 Plastic Fairing Bolt Kit
Best for: Replacing body-panel and tank-mount hardware on select bikes that use CRF50-style plastics and matching M6 hardware. It is selected for its stated pit bike fitment range and defined parts assortment.
The 50-piece set includes 16 M6 bolts, 18 self-tapping screws, four flange nuts, eight metal flat washers, and four rubber washers. A clear storage case keeps the pieces organized. The listing describes the bolts as heat-treated alloy steel with zinc plating intended to resist rust and corrosion during normal off-road use.
Limitation: Compatibility is conditional, not guaranteed by engine size. Compare the original fastener type, thread size, length, and mounting position before buying; this is a fairing-focused kit, not a complete frame-bolt set.
YD-PS001 Pit Bike Frame Bolts
Best for: Riders seeking a frame-mounting bolt set for a compatible 125cc, 140cc, or 150cc PIT PRO Trail dirt bike. This kit is included because it is specifically described as a pit bike frame-bolt set rather than a broad hardware assortment.
The listed features identify high-tensile steel mounting bolts and describe the set as lightweight, durable, and easy to install. Those details make it a more targeted starting point for frame hardware than a mixed-size general assortment.
Limitation: The product information does not provide a complete size-by-size inventory or a detailed model list. Confirm the bolt dimensions and frame fit against the original parts before ordering; displacement alone does not establish compatibility.
Greesp KLX Style Frame Bolts Kit
Best for: Owners of compatible KLX-style pit bikes who need frame fasteners. The listing names 110cc, 125cc, 140cc, and 150cc applications and cites Apollo, Thumpstar, Pitpro, Pitster Pro, DHZ, and SSR among possible brands. Its brand-specific fitment guidance makes it useful when choosing a frame set.
The product is described as a durable direct replacement. Choose it if your bike matches the listed frame style and the supplied fasteners correspond to the hardware being replaced.
Limitation: The listing does not specify bolt counts or individual measurements in the supplied features. Verify each fastener against your bike before installation, especially if the model has been modified or uses different frame hardware.
Tusk 180 Piece Metric Motorcycle Bolt Kit
Best for: Off-road motorcycle owners who want a varied metric repair assortment rather than a kit dedicated to one pit bike frame. It is selected for its mix of fastener types and stated motorcycle applications.
The 180 pieces include factory-sized metric bolts, nuts, cotter pins, and washers. The listing identifies late-model motocross and off-road motorcycles from Honda, Yamaha, Kawasaki, and Suzuki as intended applications. It also states that the bolts use 8.8 and 12.9 grades of quenched-and-tempered steel.
Limitation: The supplied fitment description names motorcycle brands and categories, but does not confirm compatibility with every pit bike. Check the assortment against the specific fasteners and dimensions your repair requires.
smseace 516-Piece Nuts And Bolts Assortment
Best for: Home mechanics who need multiple metric sizes for general motorcycle, automotive, furniture, or machinery repairs. The large quantity and range make it a flexible shop assortment, not a model-specific pit bike kit.
The package contains 516 pieces, with M3, M4, M5, and M6 bolt sizes, plus four nut sizes and four flat-washer sizes. The listing describes carbon-steel construction, corrosion and oxidation resistance, and smooth rolled threads intended to resist slipping or deformation during application.
Limitation: A broad assortment does not mean that every piece fits a particular pit bike. It may not replace a complete frame-specific set, so match thread, length, head style, and hardware type before use.
Buying Guide: How To Choose A Pit Bike Bolt Kit
Do you need frame bolts or fairing fasteners?
Start with the repair location. Frame kits such as the YD-PS001 and Greesp options are aimed at chassis mounting hardware. The Podoy set focuses on fairings and tank mounts, with self-tapping screws and washers suited to its described body-panel use. A mixed motorcycle kit can help with varied maintenance, but its contents may not match a specific frame or plastic mounting point.
How can you check whether a kit fits?
Use the old fastener or the bike’s parts information to compare thread diameter, pitch, length, head style, and whether the fastener uses a nut or washer. Compare the mounting position as well. Product references to a model style or displacement are useful screening details, but they do not prove that every version of a bike uses the same hardware.
Should you buy a model-specific kit or an assortment?
Choose a model- or style-specific kit when you know it matches the hardware being replaced. Choose a general assortment when you perform varied repairs and can identify the correct pieces individually. Pay attention to what the set actually includes: the Podoy kit lists piece counts and types, while some frame-set descriptions provide fewer sizing details.
What material details matter?
Consider the stated material and finish, but treat those details as product descriptions rather than a substitute for fit. The listed kits describe alloy steel, high-tensile steel, graded steel bolts, or carbon steel. For any replacement, use the correct fastener in the intended location and avoid forcing hardware with mismatched threads.
Frequently Asked Questions
Will any pit bike bolt kit fit a 125cc bike?
No. Engine displacement alone does not determine fastener fit. Verify the bike’s model or frame style and compare the original bolt dimensions and mounting location.
Can a fairing bolt kit replace frame bolts?
Not necessarily. The Podoy kit is described for CRF50-style plastics and body-panel hardware. Frame fasteners may require different lengths, thread types, or strengths.
What does M6 mean in a bolt kit?
M6 refers to a metric bolt with a nominal thread diameter of 6 millimeters. It does not specify the bolt’s length, thread pitch, head style, or suitability for a particular mounting point.
Is a larger assortment always the better choice?
No. A larger kit offers more variety, but a targeted set may be more relevant for a known repair. Select based on the fastener types and sizes your bike actually uses.
