Intermittent Problems with 08 450EXC?

[alec92]

Hey guys,

I'm looking at buying an 08 450EXC-R. It's owned by a car mechanic who knows the importance of maintenance. He's changed the engine oil every 500kms with Motul fully synthetic double esther 300V and the transmission oil every 2000kms. New air filter after every ride (400-500kms) and once a year it has been taken to the KTM dealer for valve checks, leakage tests, full service etc..

The bike has 8500kms (240 hours) on it and was mainly used off-road. I'm looking at buying it just to zip around town on. I might do a little bit of off-road too but mainly on-road (no high speed stuff, 80km/h max).

A few questions:
a) Is there a difference between the EXC and EXC-R?
b) Are there any problems common with the 08 450EXC? Anything I should particularly look at? If maintained properly should the engine still be fine with 8500kms?
c) I believe the 08 450EXC is a different model from the 04-07 model and is the same from 08-10. Correct?
d) The bike has aftermarket gearing. Will this affect the speedo at all or does the speedo pick up from the wheel? Reason I ask is because I'm only on my P's so I'd prefer to have an idea of what speed I'm doing.
e) If I get the bike I'll use fully synthetic oil. Is the engine oil (+ filter) per 500km and transmission oil per 2000km about right in terms of frequency of servicing?


Cheers

A.Nope just in 08 they added the R for some reason.
B. There was a problem with a few of the first ones with oil transfer, but I'm guessing that one didn't have the issue, or it is fixed.
C.Yes new bike, and different kind of motor.
D. Speedo is a sensor on the front wheel, and the gearing can be changed to what you want for little money.
E.You will hear different ideas on when to change the oil on these bikes I would say your ok with those figures.

The interval (rule of thumb I use) is, filters and oil every 1500 miles, and
oil drain and fill each other time (don't change filters).

In my 09 which is the same as the 08 the oil is different. One for the engine one for the trans. There is only one filter but two oil sumps.
