Who actually makes Mountaineer Powersports, Inc.?

What the Mountaineer Powersports filings say about the engines

Every Mountaineer Powersports filing on record is carburetted — 3 certificate rows, 2008, and not one fuel-injected engine among them.

The engine codes on Mountaineer Powersports' test vehicles —3 distinct across the filings — are led by MTNX-090, MTNX-196-08 and MTNX-244-08. The code is stamped on the crankcase and is a better search term than the badge.

All 3 filings are 50-state certifications, so every one of these machines was certified for sale in California.

Rated power across the range runs from 4 kW to 10.5 kW (about 5 to 14 hp).

The vehicle builders named are SHANGHAI POLKA RTV CO LTD and GUANGZHOU TIAHENG MOTOTRCYCLE MFG LTD — the chassis and the engine do not always share a source.

Each figure is read straight off the EPA certificate rows; the per-family pages below carry the full breakdown for every engine family.
