People,
’09 KX65 or ’09 KTM65SX for trail mostly?
Which has better low down torque?
Which has better clutch?
I want to be able to butter down whatever I get for my 9yo girl – mostly for trail riding with parents.
Maybe later – trackwork..
Yes, I have considered the KLX110 and TTR110 and CRF70f – but not real keen on the 4T at this stage..
Thoughts?

July 11, 2008 at 1:41 pm #105439Hey Byte, Have you looked at the KLX110, 140 or even a PW80, my 11 year old Girl is on a PW80, we have raised it about 1.5″ higher, and it suits her perfectly, has plenty of go to..

July 11, 2008 at 3:11 pm #105441Cam, I am a MX Coach and have been running schools for a few years now,I think that every rider is suited to different bikes at different times and the hard part is getting the bike to suit the personality, let me explain a little, a beginner around the 6-7yrs needs the soft acceleration that a PW 50 type of machine can offer, but as soon as they start to push them too hard they become dangerous because of no real braking power or suspension,( one of my boy destroyed three PW 50’s before he was big enough to ride a KTM 50) The same goes for your older riders as well, a softer type of bike is ideal up until a certain point, and now for the hard part,that point is effected by the personality or nature of the rider as well, a quite natured rider will not push a machine too hard and therefor will not need anything more than a trail type bike, but a mad lunatic daredevil type of natured rider will soon be demanding more than what a trail type of machine offers and the safest way is to step onto a motocross bike of some type for the better brakes and suspension,but if you jump up too soon the results are not good because you have a rider on a machine way too early for their skill level and then the confidence takes a beating resulting in a learning curve that is slow or worse injury, Mate the Golden rule is to keep confidence and fun levels through the roof, and be prepared to change machines when needed, I hope that helps you in some way,
DaveJuly 11, 2008 at 9:24 pm #105442thanks ktmrat.
would a buttered down kx65 or ktm65sx be ok for a mild natured 9yo girl..?
July 11, 2008 at 11:53 pm #105458What KTM rat said is so true, My oldest boy rides a XR70, he handles every aspect of the bike and bike riding. I take him out on the trails and he can do it all! If he rode a KTM or KX 65 he couldnt do that, I will let go to an XR 80 or 100 before we step up to a high performance bike at that age he will have alot of riding under his belt and know how to handle it. He rides very well, but when I let him ride a mates boys 65 he only did one lap of the track in the paddock and said he didnt like it, got back on his bike and rode till it ran out of fuel! One day he will get one! We trail ride and do mini bike club, no racing just family fun
July 12, 2008 at 12:30 am #105443Cam , be careful making a MX machine go slow, they are not designed for it and will constantly foul plugs and wear out rings, yes a two stroker not ridden fast enough or not cleared out in the revs will wear out rings and bearings real fast(been there done that- boy number 1), you probably wont like this but no the MX machine does not respond well to go slow riding, get the machine that does the job and be prepared to change to another when needed, be nice to the wife as she will think , “What The!! you just bought the other bike and now you want a different one???”
July 12, 2008 at 1:10 am #105444Thanks guys.
KTMRAT.
What experience have you had with Boy #1 about making the MX bike slower?
Cam
July 16, 2008 at 12:09 pm #105445Cam there are heaps you can do to slow them down but all things cost,some cheap others not so cheap, I have my self tried all these things at one time or another.
They are;
1. Flywheel weights to give the machine more down-low bite and less over-rev
2. Throttle stops in the carby to stop the slide lifting too much and that stops power getting made.
3. Inserts for the exhaust to restrict how fast gas can escape which slows rev rate
4. Thicker base gaskets or two standard ones, this lowers compression and makes less power
5. Vortex ignition that you set on traction, this makes a different ignition curve which slows revs down.
6. Change rear sprocket to 47 or 48 and front to 14
7. Richen carby up and it runs shaggier and lifeless, but will foul plugsMate all these things will be alright in the short term but in the long run they are not conducive to a sweet Katie thats for sure.
Let me know which things you want to know more about and I will go more in depth for you
July 16, 2008 at 12:43 pm #105446Thanks KTM RAT.
SOme great ideas there.
Others (and yourself) point out that these race bikes are not supposed to be “buttered” down lik ethis and may lead to accelaerated wear internally. Do u know of many others who have made these mods to their 65’s?
And, which one is best 47 or 48 rear sprocket ?
and including a rekluse clutch as well?
