VALTINSU has been manufacturing and exporting displacement-verified dirt bikes since 2015, serving professional dealers and procurement teams who need accurate specs, certified compliance, and reliable bulk supply across the full 50cc–450cc range.

full technical documentation provided — so your procurement team
can source with confidence, not guesswork, from a factory that
stands behind every displacement it sells.
“We've dealt with Chinese suppliers who exaggerated their 250cc bikes' actual output. VALTINSU was completely transparent — they
provided full engine specs, dyno references, and certification documents upfront. The bikes performed exactly as listed. That
level of honesty is rare in this industry.”

“We used to source different cc bikes from three separate factories.Switching to VALTINSU for our 125cc,250cc, and 450cc range cut our sourcing complexity in half. One factory, one QC standard,
one logistics contact. Highly recommend for serious dealers.”

“Before committing to a 200-unit order of their 150cc models, we requested samples — no pushback, no minimum, just clean bikes on our doorstep within the quoted timeframe. EPA docs were included.This is how professional manufacturing should work.”
