    I have been wondering what the average life expectancy of the new age 4 stroke engines is. I have an 09 WR450, I purchased this after selling my BMW 1200 GSA. But lately I have been getting the long distance bug again. After looking around on the net, magazines and the like I have noticed a growing number of people kitting out their 450’s with long range tanks and heading off on safari or long distance tours. This is exactly what I want to do. (But not to the extent that I used to on the Beemer, sometimes 1000+ klms a day). Just some good 1 or 2 day rides.

    So my question is, how long can I expect my engine to last? 5k, 10k, 15k?????

    I am very fussy with clean oil, oil filters and air cleaners.

    Thanks.

    A guy I ride with , who is in the top 3 fastest riders i know, has a 06 wrf 450 and is about to click over to 10k. He rides very hard and on demanding terrain. He is strict with oil changes and air filter cleanliness but other than that just rides.
    He had his valves checked at 9 k and no adjustment was needed. The mechanic gave the bike a full inspection and said it was in A1 condition.
    He was thinking about upgrading but after the inspection is very happy and keeping the Yammie. ;)

    They are very reliable for normal trail riding, but do not like big transports with long 5th gear work. The gearbox is the problem and if you have ever seen one pulled down you will know why!! The gears are machined out to save on weight etc and therefore do not make them the best machines for long distance work. They used to have a sticker on the bike and also the workshop manual saying Quote,” This motorcycle is not designed or intended for continuous on road use :huh:
    pleases discuss intended use with your yamaha dealer prior to purchase. :dry:
    But they have been used for long rides and performed very well, Tony Kirby used two when he rode across Australia East to west and they did the job really well and they broke the record at that time. I think its a case of horses for courses and you pay your money and take your chance. :)

    My 09WR450 has done 3000km ++ with some hard riding, 2 x Yellow Mountains, Club Enduros, & Finke to name a few, did a topend check & replaced piston & rings earlier this year. Was like new all within spec, just a light deglaze & put it back together. This bike has been held wide open for long periods, flat changed & looked after mechanically.

    Fitted a Cush Drive rear hub earlier this year & it has taken all the harshness out of the bike, noticeable at all speeds.

    Rumour is a WR450 without Cush Drive can’t handle a Safari, Fit a Cush & it does it easily.

    My previous 05 & badbowies 04 had done their fair share of k’s with no problems

    Hey lads. This thread is Music to my ears. Just bought the 2010 WR450 and have 300kms on the clock. Was planning to do a few trips on the new bike. That Camerons corner ride looks good….

    Last bike was 05 CRF 450 X.
    Had the Honda since new. Rebuilt top end twice .I think the manual says every 100 hours so thats when I did the first rebuild. $$$$ouch. (I wouldn’t know how many hours it was when I did the second rebuild as the electronics had long ago shat themselves…)

    The WR seems a lot smoother ride. It is more powerful out of the box than the Honda was but then again it’s 5 years newer so it should be better.

    Seems like all the guys I ride with are team blue. Their bikes never seem to stop.
    I was fighting the change and being one of a rare breed of team reds.
    Gave in and got the team blue with a free pressure washer and pit tent for $10500 inc GST.

    Now my kids and I are all team blue.
    Long live Yamaha (even though Valentino has gone Ducati)

    Boulders on the money they wont do long transports even with a cush drive, cush drive will get it further but the bike the gearbox final drive etc isnt designed for it..

    SB_250y’s 450, of the 3000kms racing klms half wouldn’t be top gear and it would have got an oil change every 500kms at the most if not every 240kms at each end of finke etc. With touring oil changes would be much more then that.

    Get something designed for the job, it will enjoy it, you will enjoy it much much more and do it in comfort with less stress.

    Most touring bikes do 40 to 80k standing on their head, a 450 enduro bike no way known in a touring role

    Thats why they make different bikes for different roles IMO :)

    Yes the oil gets changed @ each end, wouldn’t like to do many more k’s without an oil change as the oil is black as & stinks, still only do a filter every 2nd oil change no matter what the interval.

    My point exactly, thats 240 racing klms and its rooted, its certainly not going to do 2 or 3k touring without the same. Oil capacity is the killer as they hold bugger all oil and arent designed for it

    There is no way I would use a wr for touring. Like has been said before they love oil changes. This is not a criticism of the bike. They are great bikes and the pick of the enduros but that is what they are, enduro, not touring. Like TB said if yamahas had an hour meter standard I reckon SB would be very surprised what his average speed is. Most enduro bikes I know, even counting blokes that race are lucky to get an average speed of over 40 km/hr.

    I’m not sure how much difference a cush drive makes but riding a standard wr on the tar at a constant speed even feels wrong. I guess this would change a bit if my bike was geared for tar speeds.

    There are a lot of good touring bikes that are cheaper than the wr anyway.

    Be very careful stating information about someone you don’t know, I know what my averages are. I did say my bike had been held wide open for long periods though. Unlikely anyone would do this for any period of time using it as an ADV ride. With the correct gearing they will happilly sit on 120k

    If you want to try a cush Drive WR you are more than welcome to try mine. I have done an 500km ADV ride on my old WR without Cush with motard wheels & I know the difference.

    from my experiance the wr400 moter is reliable had one for six and a half years rode it to work for 18months or so and trail rode it most weekends with no problems changed the oil heaps but hated it on the highway. lasted longer than my xr400 that got the same treatment

    I am with Bundy (sorry SB :( ) You would be surprised by you average speed and how slow in can be when in fact you think you are flying. Take Yellow mountain this year for yourself. Its say with the sections cut out 420kms total, you did it in a total time of 6hrs and 21mins. That give you an average speed of 67.63kms per hour. Having raced Yellow mountain myself a few times I would have thought it was faster then that. Finke would be the only average faster speed event that I have seen. An average single track day cab be in the 20’s or 30’s. :ohmy:

    Sorry TB

    40k’s is less than 2/3 of 67.3k. I can do maths no problem

    Never said I rode at extremely high speeds all the time, all taken out of context

    Someone quoting stuff without knowing or having riden with me, is the point I was making.

    I don’t prejudge other peoples ability & style so they can leave mine alone
