The Honda CBR125R and Yamaha YZF-R125 have dominated the sales charts, regularly being the outright top-selling bikes in the UK.
But now there's a new contender - the Derbi GPR125, complete with upside-down forks, underslung exhaust and a race-look dash that even has a lap-timer and top-speed recorder for some serious style points.
To find out if the Derbi GPR125 can hold it’s own against the class-leading Japanese machines, MCN turned teenager and rode all three to the Silverstone MotoGP, laden with tents, barbecues and booze for a lads' weekend.
So will the new Derbi GPR topple the competition? Have your say in our online poll below.
You can read the full test in next week's MCN, on sale 30 June 2010.
