Featured Projects

Triumph 750 Triple S4RR

The machine that started it all for Framecrafters the 1970 Triumph 750 Trident. Inspired by Rob North and Colin Seeley, Randy Illg and said time partner Jim Carlson built frame #1 for his Triumph Triple road racer. Originally raced as a production bike from 1984-1988 it was then transformed into the "Red" Formula 750 machine in the winter of 88'-89'. Retired in 1993 having been raced to some regional titles the machine took a semi-permanent residency in a dusty corner of the shop. In 2005 Karsten Illg , Randy's 2nd son, took the initiative to bring it back to life. While making some revisions to the original frame design the machine slowly began its road to restoration. Eight slow years of rebuilding, refinishing, replacing parts and pieces the machine transformed. Not having been on a track in 20 years the FC #1 Triumph Triple (now blue) was successfully raced at the AHRMA Road America event in June 2013. Piloted by Karsten Illg in the Formula 750 class he managed a 2nd place.

FC FAT Featherbed Triton

Framecrafters FAT Featherbed is a new twist on an old classic. Modeled from an original Norton Featherbed Slimline frame FC has made a few improvements over the original design. The fitment of an additional tube from the steering head back to the mid-chassis cross tube significantly reinforces the steering head while providing a more secure location for mounting the top motor mount. The swingarm mounting point at the frame is now 1" wider on either side. This change allows the use of the Triumph Hinckley twin motors (shown in pictures)amongst other new choices. Additionally a 5" rim and wider tire can now be fit. As with most of FC's frame kits we can tailor each one to meet an individuals specific needs.

Kawasaki KZ1000 Cafe'-Fighter

Starting life as a 1976 Kawasaki KZ1000, this machine underwent major updating and revisions. From the frame up every component has been modified to raise the performance standards while keeping the 70's era air-cooled muscle engine
