  1. with heavier fork- springs the handling is away
  2. sorry sorry, had not seen he is a boy. For that KTM is right and very good. But please the smaler sizes 65 or 85cc with different wheels.
  3. Honda CRF250R is the best bike for you!
  4. Take a CRF250R up from 2014. Ride and have fun with that bike. Best cornering and engine characteristic for you.
  5. Buy a KTM 450EXC or a Beta 450 Enduro. Than you have all you need and much fun.
  6. Buy a KTM EXC 450 or 500 up from 2014
  7. Buy a KTM 300 EXC up from 2013. You can do everything with this bike.
  8. Go to KTM and buy a 350 from 2016 or 2017. That is the gun for younger riders.
  9. Buy a KTM. Is the better bike i think. Honda has now in 2017 not anymore different gearbox oil, heavy weight and handles not better as an RMZ 450 from 2009. You have although to invest in a good chain, fork mods, ignition mods.
  10. Hello, first a Happy New Year to all and JD! Have bought now a JD Kit from Thumpertalk and now fixed it for my 07 CRF450 R. Rest of the bike ist stock. My current setting: JD red 3. 190/42/1 3/4 bike rans to fat i think. What to do? What jetting are you running??? 100 meters from sea - level-10 degrees celsius now. 4stroker

I changed the main-jet from 178 to 174 changed the pilot-jet to 45 What to do? an other cam, change carb-setting, change to jd-jetting??? what sizes of jets? I live in northern-germany (sea-level) 2th place sen. 2008 4stroker
