KTM 640 vs 690 gearing question ??

So l had a 05 640 ADV until it was stolen, it was my do everything bike.
across the country to Enduro racer, once set up it was great but the gearing was to close.
would do the counter socket swap at trail head, but it was always balancing act. if l could roll tight single track and hills in second gear it was a monster, it was amazing the difference from 1st.

so my question. 690 any better, i want to be able to roll single track in second but still cruise at 70mph.

640 with a pumper is real good

Although the 690 has a 6spd box the total gear spread is a touch less than the 640's 5spd.

However after doing a few miles on a 690 I reckon with the smoother motor it could quite happily be geared down to a bit lower than the 640, without getting too vibey at 70mph. Technical single track in 2nd might be a big ask though.

Cheers
Clint

The 690 ratios were originally chosen for supermoto competition. Maybe some day KTM will build an adventure variant with a wider gear spread.

See five-speed vs. six-speed -- some surprises http://advrider.com/forums/showthrea...281742&page=18
