COMPONENTLikely #1 Supplier/Origin Country for AmericaSourcing NotesSourcing (And Links, If Any)
3
Motorcycle ECU units in AmericaJapan or Mexico (via Japan/Germany)While Japan/Germany are design/tech leaders, some assembly might occur in Mexico due to NAFTA (USMCA).
Finding exact US-only supplier data is tough. 		Source: Gen. Industry publications, NAFTA/USMCA trade flow data.
4
Motorcycle aluminum parts in AmericaVaries Highly. Likely China and MexicoChina for mass-produced castings. Mexico due to USMCA benefits (cheaper labor, proximity).
Much reliance on imports. Ultimately, This option varies with too many contenders to pick a clear #1.		Source: Trade data (US Census Bureau, etc.), industry publications.
5
Motorcycle tanks in AmericaVaries. Possibly US or MexicoSome US production exists, esp. for specialized tanks (e.g., Harley-Davidson).
Mexico is a strong contender due to USMCA and auto industry infrastructure. 		Source: Limited public data, gen. industry insights.
6
Motorcycle wheels in AmericaVaries. Likely China, sometimes JapanThis category contains major import dependency. China is a major source for mass-market.
Some specialty/aftermarket wheels may come from Japan or the US.		Source: Trade data.
7
Motorcycle fairings in AmericaVaries, high import rate, ChinaThis category is affected by high import rates.
China is a major source for many OEMs.
US fairing mfg. tends to be specialized/aftermarket. 		Source: Gen. Industry knowledge.
8
Motorcycle third-party manufactured parts in AmericaLikely China and AsiaThis category is extremely import-driven, hence the results will be too varied for a clear #1 contender.
China and other Asian economies are major sources of small parts, hardware, etc.
US often handles assembly, not part production. 		Source: Gen. Industry reports.
9
Motorcycle engine components (crankshafts, bearings, etc.) in AmericaVaries, but likely imports. Some possible US production.Multiple parts, multiple suppliers, ergo hard to pinpoint a clear #1 contender.
Precision parts may come from Japan, Germany, or the US.
Larger volume can be sourced.
Imports are, again, a substantial factor here. 		Source: Automotive supply chain knowledge (some overlaps).
10
Motorcycle steel chassis in AmericaVaries heavily. Likely MexicoUS steel capability exists, but chassis production for entire bikes is limited.
Mexico is more likely due to USMCA and auto infrastructure. 		Source: Automotive/heavy manufacturing data, anecdotal evidence from industry.
11
Motorcycle aluminum chassis in AmericaSame as steel chassis Varies heavily. Likely MexicoHigher-end, specialized frames are more likely to be manufactured in the US, but overall production is limited, Mexico is more likely.
USMCA considerations play a significant role.		 Source: Gen. industry news.
12
Motorcycle exhaust systems in AmericaVaries. Import-heavy. Aftermarket more likely USOEM exhaust is often imported, while aftermarket may have more US manufacturing presence.
China/Taiwan are big sources. 		Source: Gen. Motorcycle parts industry knowledge.
13
Motorcycle transmissions in AmericaLikely imported (Japan)Japanese OEMs (and their suppliers) are key transmission players.
Even with US assembly, transmissions often originate from Japan or their Asian factories. 		Source: Gen. Industry/OEM knowledge
14
Motorcycle batteries in AmericaMexicoBattery components often imported (China, etc.), but assembly might be in Mexico to serve US auto/powersports.
USMCA is the big driver. 		Source: Automotive supply chain reports.
15
Motorcycle windshields in AmericaLikely imported (China)This category is largely influenced by the import market.
China/Asia are cost-effective leaders for windshield manufacturing.
US has niche/aftermarket producers. 		Source: Gen. Industry trends.
16
Motorcycle handlebars in AmericaVaries, Import-heavyHandlebars are diverse...Imports are, again, very common for this category.
Some US mfg. may exist for custom/specialty. 		Source: Gen. Industry analysis.
17
Motorcycle suspension systems in AmericaLargely imported (Japan/Sweden)Japanese (Showa/Kayaba) and Swedish (Öhlins) dominate.
US assembly is limited.
This is a high-tech area, ergo is influenced by countries giants in the suspension well as rider preference.		Source: Gen. brand knowledge
18
Motorcycle brake calipers in AmericaLargely Imported (Japan, Italy)Japan (Nissin) and Italy (Brembo) control caliper tech.
US manufacturing is low.
Imports are heavy for this category as rider preference is for both Nissin and Brembo. 		Source: Gen. OEM/industry knowledge
19
Motorcycle brake discs in AmericaLargely Imported (Japan, Italy)Discs are similar to calipers.
There is some Japanese/Italian influence for this category.
US is mostly small aftermarket demand here. 		Source: Gen. Industry analysis
20
Motorcycle brake pads in AmericaChina and Asia (for OEM)OEM may rely on bulk, affordable pads.
US tends to have performance, aftermarket options here. 		Source: Gen. Automotive supply chain knowledge
21
Motorcycle wiring in AmericaMexico or Asia (parts and harness build)Wire parts import, assembly in harness may be in Mexico to reduce labor costs, parts from China/Asia are very common due to cost. Source: Gen. OEM automotive industry publications
22
Motorcycle fuel lines in AmericaMexico/China (likely for parts) and US assemblyHoses may come as parts, Mexico to build the harness, but much of the line assembly.
US has more advanced systems available at an increased premium by comparison. 		Source: Gen. Automotive fuel system technology.
23
Motorcycle engine oil in AmericaUS (for blending/packaging)Oil blending and packaging is largely US.
Refining and base oil sourcing is global. 		Source: Oil industry reports.
