About me: (so you can put my opinions into context)
I'm a seasoned rider. Middle aged male. I ride about 15~20K Km pa. Past rides of note: Suzuki Burgman AN650. Honda CTX700 DCT cruiser. I still have a PCX150 which makes me feel like a 9 year old on a skateboard but I need something with slightly longer legs and better suspension for our less than perfect roads. I don't have a left ankle which is why I developed a fascination with scooters and the DCT Honda, however the shift on the DL250 is so light and easy I can manage it quite easily (I'll eventually put an over/under shifter on it).
My DL250A:
It came with handle bar risers, knuckle guards and a center stand and 600 on the clock. It's just had it's 1000km service. I love the handling. It's steady as a rock in all conditions but still turns readily. Two criticisms: (1) owners manual says valve clearances need checking every 5000km. That means instead of an oil change you're looking at a $400 service (in Oz) every 5000km. Feedback from GSX250R & Inazuma owners say it's not needed. (2) The gearing: best suited to hill climb competition or hard core off road stuff. Mine isn't properly run in yet but with the std gearing it would pull away from 40km/h in 6th gear. I don't need six gears to get to 40. It's frustrating shifting through redundant gears if you're just commuting & not racing. I tried a 15 tooth front cog but it wasn't enough. I've now gone back to a 14 front but with a 39(instead of 47) rear. It now feels 'normal' - cruising at 100km/h (indicated 108) now comes up at 6800 rpm instead of 8000(about) - so much more relaxed - still plenty in reserve. Also the gears are now more spread so a burst of throttle in 1st will give you a burst of speed instead of having to shift through 4 gears before you cross the intersection. The 39T rear cog cost me $55 so no big deal but Mr Suzuki, What were you thinking? The DL/GXSR/GW250 is a small but torquey motor so you can shuffle around town (or on dirt trails) at lower revs in quite a relaxed manner. If you need power, let the revs build to over 6000 and the engine feels quite spirited (some vibration but not a big deal). My tinkering with changing cogs etc has given me the impression that the DL250 is well built & solidly put together. I love it - highly recommend it but I'd budget for a rear cog change if you're considering one.
