Considering buying a G450X but...
« on: February 13, 2017, 08:11:40 pm »
Hi all,

I'm considering buying a G450X but it has issues, the most serious of which seems to be that in 3rd or fourth gear, if you open the throttle wide, the engine revs and the bike does not accelerate. From what I've read about the G450X this can be down to a worn torque limiter. This thread goes into quite a lot of detail: http://g450riders.org/forum/showthread.php/118146-Torque-Limiter-prices-going-up-for-our-G450X-motors

Has anybody got any knowledge or advice?
Is there any way to confirm that it's the Torque limiter (vs the clutch) without opening the engine? What would BMW charge to do this?
I'll call Donford BMW tomorrow for a price, but has anybody here dealt with this issue and what did it cost you?

One piece of advice I received suggested that I do an oil change which could rectify the problem if it's a clutch issue. What is the recommended oil locally? Castrol Racing 1 4T 5w40 ?

Any suggestions appreciated...

That's always an option :-). but if the seller is willing to drop the price but the cost of the repair it may still be worthwhile.

Good idea - I've bugged him twice already with other questions and I'm not sure he'll know the answer but he might know who will...

You can also speak to Jandre Koekemoer.

Works on many of our 450's and knows them pretty well.
Hope is a good thing, maybe the best of things, and no good thing ever dies

Ja - clutch or torque limiter. The clutches are hell good tho so its prob the torque limiter.
To change it is not rocket science. In fact I have a spare if you interested.... BUT - it requires dropping the engine. Again - not that much of a mission but you need to know how to do it.
Oh - I also have a spare clutch if you interested, so ja - I have the parts you need. But someone has to disassemble.
You would be advised to do the torque limiter bearings too - easy to source.
PM me if you need any advise or parts.

if u are interested in something no matter what it is, go at it full speed ahead, luke warm is no good, hot is no good either, white hot and passionate is the only thing to be...

Moerse thanks for the offer Peter. I've ended up buying a G650x because the 450 I've been considering is basically another "project" and I already have several of those. I promised myself at the beginning of this year that this was  the year to FINISH some projects instead of buying new ones! e.g. the XT500 that I took apart in 2010 and the BMW R100RS that dropped a valve in 2015...  :-[

I still have the 450 in my garage...so let me chat to the seller and we'll see.....imagine owning a 450 AND a 650  :ricky:

I learnt the little I know from Big Dom, and Bonova, and others, and I too would guess torque limiter, and I too think Jandre Koekemoer is a very good option to ask; he maintains my bikes, including the G450X, and was working on these bikes back in the day (2008/2009/2010) at Hamman Motorrad.

Good luck
Chris

PS: I feel that the 450 and the X650 are 'fairly' close in SOME ways, and I think say an 800 or 1200 with a 450 makes more sense, maybe?
