Used Exhaust - RS125 NX4
Used Exhaust - RS125 NX4
: $275.00

Used exhaust for Honda RS125 (fits all NX4 '95-on) but believe this to be from a 1998 model.

The stinger has had a repair done, as so did from this range. It was not uncommon to snap the end off in a crash. The repair is one of the nicest that I've seen. Looks solid and very usable.

Used VHM Deck Height, air density, and case
: $350.00

Use VHM deck height gauge. Will work on any of the 125cc cylinders. TZ125/250 and RS125/250. Looks in new condition.

Also Langcourt brand air density gauge. Excellent to get a quick read on jetting changes.

Has weather station too, but needs fresh batteries.

Comes in a nice safe Pelican case so they don't get knocked around during transport.

Great for getting a consistent setup.
