Below, we get the full story on this custom dual-sport.
Honda NX650 Scrambler: Builder Interview
• Please tell us a bit about yourself, your history with motorcycles, and your workshop.
Martin Kvarnhult, 39 years old, Sweden. I have a small workshop in central Örebro. This is my first build, but definitely not my last.
• What’s the make, model, and year of the bike?
Honda NX 650 Dominator, 1991
• Why was this bike built?
I realized you can’t buy a bike like this, and I really wanted to have one, so I bought a stock Honda NX650 Dominator from 1991 as a donor bike. A couple of things was important for me accept the design:
• Function, As I will ride the bike daily.
• Clean, minimal subframe (without battery box etc.)
• Street legal (almost)
• What was the design concept and what influenced the build?
Wheels from Honda SLR650 that I sandblasted and powder coated. Tyres are Continental TKC80 Front : 110/80 – 19″ Rear : 140/80 – 17″
Sub frame chopped of and a new hoop/brat style sub frame was bent in my shop using sand filled 22mm tubes and then weld everything in right angle. Frame is then sand blasted and powder coated satin black
Gastank is Honda CB125 K5 from early 70s that I made dent free with hot glue slide hammer. Inside I made it rust free to add 1000 grams of citric acid and 8liters of hot water and let it sit for 24h, works great. After that I painted the gas tank gloss white (RAL9003) 2part for gasoline resistance by myself.
Motor is cleaned and re-painted with 2part epoxy paint. Open K&N air filter. Carburetor is pilojet 48 – main jet 170 with needle schimed up with a washer.
Exhaust is built and designed by myself from 38mm stainless steel tubes and fittings, just tack welded on place to get the 100% fit. Wrapped “headers” with Titan exhaust wrap. GP style slip-on is street legal in Sweden.
Battery is replaced by a much smaller Lithium battery that is hidden under the gas tank. Together with CDI and fuse box In a custom metal box
Seat is padded on an aluminium seat pan and stitched — all of it is done by myself on my mothers stitching machine.
• How would you classify this bike?
• Was there anything done during this build that you are particularly proud of?
