DB MAGNUM

LEM RX65

POLINI

If you are interested in a KTM Pro Junior 50cc auto race bike you might want to consider some of the following options.

We have stocked KTM bikes in the past, but not since the factory discontinued the Pro Junior from the model range. 

What are the alternatives?  Check out the following guide to see what other bike fits your criteria best.  Even better, give us a ring on 01386 701162 & ask us for advice

PRICE – If your reason for considering a KTM was that it is competitive at an affordable price, with the DB Magnum the price is under £1,000. 

POWER – The Pro Junior factory quoted power is 8.5bhp (approx), raised to 11bhp with a 21mm carb.  If you want more power, the POLINI X1 produce 12.6bhp in liquid cooled form.  The LEM R2 & R3 produce 11bhp in air cooled ready to race form, as does the DB Magnum.  If you wanted to limit the power for a novice rider, a smaller carb will do the job for under £100.

SEAT HEIGHT – Seat height is a big thing to help boost a young rider's confidence, and so matching the correct seat height is sometimes more important than outright power.  The KTM had 58.5 to 61cm seat height (adjustable), LEM R2 60.5cm, R3 67.5cm, Polini X1 61cm, X3 72cm and DB Magnum 67cm

EXTRA POWER – If your rider is maxing the bike out, extra power & tune up bolt on bits are a must, but what’s available to give them that edge?
