A chopper style with a simple silhouette, finished with 2%ER’s original parts.

It’s assembled with all unprocessed bolt-on parts, and the owner-specified yellow/red flame pattern is painted on the original gasoline tank by “BACON“.

The front fork, extended by a total of 30cm with long inner tubes and fork joints, is set with a 2° rake triple tree for improved silhouette and handling.

Custom List

FrontHandlebars, F forks, headlights, etc.

●We have extended the front fork by 30cm to make it look like a Chopper, changed to a 2° rake triple tree to maintain nimble handling even with this fork length, and selected small-diameter tires.
