07 ktm sxf250

[xr-rider]

so how much to do the big end, piston, top end

[flyingcr250]

Thats a different bike, and the exc 2stroke range are ment to be very solid bikes, and what you have written sounds about right.

We are talking about the 250sx-F

oops sorry. BUY A 2STROKE BWWAAAAAP!!!

so how much to do the big end, piston, top end

$1400 parts, $600 labour....apparently.

That sounds ridiculous. Haven't dropped a trailing zero, have you?

My mate's been racing his '07 525EXC in motards, street races & cross-country. It's got a motard cam etc so it's noticeably stronger than a stocker. Top-end rebuild at 150 hours, bottom end not touched yet.

no zero dropped running slipper clutch prob dont help

The japs were cheaper for parts on ebuilds, and top every 80hrs, crank around 200hrs.

Dunno about that, have my bike on 65hrs on top end atm and has no-where near the power of a newer top end. I know this as fmx ramp i usualy hit in 2nd requires 3rd. As for crank at 200... Mine went in my CRF at 40. For no reason at all. $2100 in bills, and that was with the spares kit that came with my bike, so who knows how much It would have been If I had to pay for everything.

yeah but hold on, your compareing a 525 to a 250, generally rev the 250 alot harder than a 525, the 525 is a exc and the 250 sxf. the 525 doesnt have to work as hard to get the power the 250 gets, shall we compare apples with apples instead of apples and penuts??
alot of the mataince comes down to the oil changes its gets, my husky requires oil changes at 16 hour intevals but i service at 5 hour intervals, then i know its always right. oil and filters are cheap when compared to rebuilding engines all the time!

I woulda thought a slipper clutch would have eased the load on the engine by absorbing some shocks? Or does it allow one to get away with more brutal downshifts?

[warewolf]

Which is also shownup in my sisters partners ktm525sm he races it and only get 10hr yes 10hr out of the bottom end

yeah but hold on, your compareing a 525 to a 250

No I'm not The thread is about the 250, but I was responding to the post (above) about the 525.

[barty5]

they run a workshop and service bikes think they know what they are doin. and yes slipper clutch let you change a lot harder.

my mates dad is looking at getting an 07 ktm sxf250. is there any thing you have to look at on these bikes? do they have any problems? how easy is it to get parts for them?

Thanks in advance

i got one, but don't ask me about anything mechanical, as I just give it to the shop and pay my money. It is an excellent MX bike, looks good, rides well on open trails, I have difficulty with it on tight trails. I have got heaps of youtube footage, just click on my link below.
As I am a trail rider, in hindsight I would get an EXC, as I want a bloody electric start!. And after hours of riding your butt hurts like hell, as the seat is not designed for trail riding.
It is nice and light, about 98kg's, and keeps up with 450's, just with less torque out of the turns. And for some reason, it is a bitch to kick over when I drop it (happens a lot) haha
