Sorry Volroom, can't help with pitch story. I have, over the years, developed a strategy of ALWAYS shopping for parts with a sample in hand. I always get the right thing. I wouldn't change sprockets if you got given the wrong chain. You'll make a lifetime of fishing in the wrong river. I would urge you trade the chain.
Having just said that, I ordered a new front disk brake rotor from Suzuki , with no sample !
The model numbers and codes for this generation DR are all over the place, so I've just phoned in with my VIN # .
Yes it IS a 1994. The designation of mine is DR650RE , with year code "r" for 1994 , so it's a DR650RER supposedly.
The internet is a great place for total misinformation. FINALLY, I know what my bike is, from the official Suzuki Fiche.
My new disk is inbound from Japan. With my Frequent Flyer discount it's around R2800.
The confidence factor in the metallurgy of the clones is a ZERO. On brakes, I take no chances.
I'm in on this bike ... call it R40k.
No matter how you hack it, to get a mechanically new and completely reliable machine on the road, with a whole new life expectancy from a whole freshly rebooted platform , it is unlikely you will end up spending any less.
