Most guys put topends in around 400 hrs on bikes that see typical use, if it's been raced or ridden hard then adjust downward accordingly. AS for bearings, replacing those are pretty rare but I'd imagine around 600 hrs it'll need the crank done. One of the characteristics that comes with this is decreased oil capacity. The 250L has an oil capacity of 1.8L, meanwhile the 450L, a bike with 200ccs more, has about 1.4L of oil capacity. So with a much higher output engine, that will be ridden hard, and will generate more heat, and has even less oil capacity, the oil change intervals need to The shop told me to change the oil every 300 miles and I just did my first 300 mile oil change. However, the oil came out pretty, clear and red just like the fresh oil I was about to replace it with. The shop also said if I was on the street most of the time that I could change the screens and filters every other oil change but to clean the The KTM 390 Adventure has a 4650 mile / 7500 km or annual minor service interval, and a 9300 mile / 15000 km major service interval. At the minor service, change the oil and air filter, and run over the list of checks for leaks, wear, and degraded materials (e.g. rubber hoses). Read the manual and buy exactly what it specifies (period). I have a KTM 450 Exc and read up on this same issue. For mine it is the Motorex 20w50 since i live in so cal. Although manufacturers may have the same viscosity (ex 10w40), there are additives like graphite that are added for optimal engine wear based on your engi Its 80% trail 20% road bike. A versys or african twin or vstrom or some other ADV bike is perfect for what you are looking for. Those are great pavement bikes that never need maintenance. The 450 needs about 4 times as much maintenance as the 250 or any of the 650 dualsport or adventure bikes. The KTM Quick Release poly skid plate, makes for very easy oil changes, if you don't ride an area with a lot of jagged rocks. I just put the 13L tank on my bike - now it is a 2 bolt affair to remove both the tank and seat to gain access to the head. Easy as pie. #13. jbrownmxr , Feb 19, 2008. The crankshafts with strokes of 63.4mm (450 XC-W) and 72.0mm (500 XC-W/EXC) with ultra-lightweight conrods are made by Pankl from special high-tensile strength steel. The crankshaft employs a K0iV.
