Rider Profile

Best ForThis is a beginner-friendly mini-enduro, well suited to young or novice riders learning throttle and clutch control off-road.
PurposeIt is built for light trail riding, recreational play, and low-speed off-road exploration rather than any serious performance use.
Rider FitThe small 106 kg frame and 820 mm seat height make it manageable for smaller or lighter riders, though the seat height is tall relative to the bike's tiny displacement.
CharacterIt has the playful, low-stakes personality of a small-bore trail bike, with modest power delivered through a simple air-cooled 125cc engine and kick starter.
Not Ideal ForThis bike is not for highway travel, long-distance touring, carrying a passenger, or any rider seeking real speed or power.

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

Feet:

At 820mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with balls of both feet on the 2023 Apollo RFN Thunder 125, with a cramped knee angle of around 70 degrees and a slightly forward riding position.

Data quality: estimated (wheelbase estimated from this category's typical bike, not this model's own spec). 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.
