good on you mate
maybe something to submit to Suzuki. the DR is long due for an update...

13,000kms is nothing, im surprised he still owns a Suzuki :D

Are there any tell tales noises or shifting abnormalities beforehand? Or is it just 'BANG'? :huh

Are these prone to failure? Hmmm. I've had two of them (both 1996). Sold the first with 10.000 miles on it, and the second with 30.000. Both were problemless.

What damage to the motor occurred in those scenarios? Or is it the transmission that got destroyed? Why do you think third gear is significant?

To be more objective, maybe tally blowups that occurred in other gears, as well.

Honda XR 600s have blown third when run hard since their inception,I dont think Honda ever address'd it. 4 DRs out of how many out there? hard to call it a trend but maybe more will chime in.

DR650 3rd gear blowups...

NordieBoy (NZ) 2001 60,000km
Transalper (NZ) 2001 55,000km
Rosscoact (AU) 2004 13,000km
Mardy (US?) 1997 53,000km
TH (NZ) 1999 40,000km
RubberCow80 (AU) 2001 25,000km (2nd gear?)
Philth (AU) 3 bikes <20,000km (2nd gear?)
BikeRooter (AU) 2006 10,200km

I'd probably put the 2nd gear ones as Aussies tanked up on fourecks being confused about this "counting" thing.

I'm starting to think it's 3rd gear itself. The design of it with the thickness of the metal and the selector grooves and the more you use 3rd gear under load. All the low mileage ones are Aussie with quite possibly heavy 3rd gear sand use.

Low revs going up a slight hill and it was a drawn out cruuuuuunnnnch. I thought the chain had come off to start with.

No warning at all.

Looks like the engine gets totally destroyed - gears/cases/bottom end/conrod/piston...

3rd gear is right in line with the big end.

I think it's the shape of 3rd gear. Where the dogs are in relation to the teeth and the selector groove weakening it as well.

Hunh!!
I guess i was too quick to bust balls.:rofl

NordieBoy 01-18-2009 01:13 AM

Anyone who had a blowup...
Did one of the selector forks have both arms broken off?

Just wondering 'cause if they broke whilst in 2nd gear 3rd may have tried to mesh at the same time...

snpl 01-18-2009 02:14 PM

I have a '96 model with 135.000km on it. 2nd gear was moving to neutral as rpm's got higher.Shifting lever was also vibrating between 2nd and neutral.I dont know if my gear problem has something to do with yours but since i disassembled the engine to find what is wrong I will post below what i have found.
