    Intermediate Riders, Children that have fully mastered basic motorcycle control
    The Kawasaki KX range are proper 'mini-motocrossers' that children can progress to once they have mastered the basic riding and control skills on the Yamaha PWs and/or Jianshe JSs. The KXs have 6-speed, manual gearboxes and long-travel suspension. These bikes are ideal for learning clutch / gear control and developing more advanced riding techniques such as handling jumps, flat and berm cornering, etc. The KX60s typically suit children between 5-7, whilst the KX 65s are designed for children in the 7-10 age range.

    Testimonial from a father appreciating the range of bikes-
    Dear Simon

    I just wanted to send a few grateful words of thanks to you all for getting Joel started in the world of motocross.

    Joel has recently been diagnosed with a complex dyslexic auditory processing disorder which makes the progress Joel achieved at CYR a real testimony to the excellent tuition received. The auditory processing disorder was diagnosed following an independent educational physiologist's assessment. The assessment highlighted that Joel struggles to digest/react to verbal instructions and that this can hinder his approach to learning. This has also had a negative impact on his self confidence.

    When we consider how reticent Joel was when he started to learn to ride at CYR to the progress that he made from the PW80's, to the KX60, KX65 and even jumping a KX85 over the freestyle ramp it goes to prove that the teaching methods utilised by the team at CYR work for all abilities.

    Joel is nearing his 11th birthday (May) and continues to enjoy riding motocross.

    Once again a big thank you to you all.

    Kind regards
    Sean Harsent

    Intermediate / Advanced, 10+ yrs Older children who possess motorcycling skills
    The Kawasaki KX 85s are highly tuned, competitive moto-crossers designed for children over 10 who possess intermediate to advanced skills. The KX85s come in two formats - The 'small wheel' version aimed at 10-13 yr olds and the 'standard wheel' version for 13 yrs and older. With the exception of the wheel size, the bikes are identical. CYR restricts power output while riders are learning clutch, hill-starts and jumping.
