Rider Profile

Best ForThis 50cc naked is aimed squarely at learners and young riders taking their first steps on two wheels, often under a moped or restricted license.
PurposeIt is built for short urban hops, commuting to school or work, and light city riding rather than any kind of serious performance use.
Rider FitThe low seat height and light dry weight make it very manageable for smaller or less experienced riders to handle at a stop and in traffic.
CharacterIt has a sporty, naked-bike look with a perimeter frame and upside-down fork that mimics larger bikes, giving it a fun, nimble feel around town despite its tiny engine.
Not Ideal ForThis is not the bike for highway travel, two-up touring, offroad adventures, or anyone seeking real speed or power.

2007 Rieju RS2 NKD Rider Ergonomics Assessment

Calculated in your browser only - your height/inseam are never sent to our servers.

Feet:

At 800mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with both feet flat on the 2007 Rieju RS2 NKD, with a moderate knee angle of around 115 degrees and a slightly forward riding position.

Data quality: measured. Assumes about 30mm of suspension sag once seated (a typical street-bike rule of thumb - stiffer or softer suspension will vary). This is an approximation from category-typical geometry and generic body proportions, not a measurement of this specific bike or you - sit on it before you buy.
