I have a suzuki SV650, '04 with 1750mi on it.
I need to replace the tires. Dunlop says 36/42 psi and suzuki says 33/36. The wear looks like underpressure is the cause. I don't ride the bike hard; check the pressure every time I ride with a decent gauge.
At 36/42 psi, the bike now turns easily, something that didn't happen at the lower pressures. The suzuki rep claims this pressure scheme (33/36) was developed with Dunlop. He thought the fork or steering bearings might be the problem. I don't believe him. Dunlop wasn't sympathetic, either.

I'd hate to tell you something other than what the dealer and mfg suggested but on street bikes I always have better luck at 42 to 48 lbs.

ONLY 1750 miles? Something is VERY wrong> After all, you're not running V-MAX...and even that bike gets 3000-4000 miles on the back tire.
You should be getting...about 8 thou out of the rear tire and 14 out of the front. At least that's the way I think I remember my Hondas and Yamahas....

I have 13 street bikes and I will NEVER put a Dunlop tire on any of them anymore. Wore out the front tires (Dunlop, factory installed) on two bikes BEFORE the rear. When I attempted to discuss this with a Dunlop Rep during a rally, he gave me the "go pound salt" treatment.
BTW, where does Dunlop say what the right pressure is? On the tire? Beware that THAT number is the recommended max pressure under max load for the tire, not what you should run on a particular bike. Anything over 40 PSI cold on any streetbike is not smart.

I have never heard of anyone wearing out a front tire that quick. I have only heard of a few that did on the back. Those were on powerful bikes with some aggressive riding. It sounds like you have a problem but I sure wouldn't know what it would be.
Riding since 1966. Currently have 2 ST1100's, 1 ST1300 and 1 K1200LT

bike makers suggest the lower pressures because it improve the ride.
but higher pressure gives you better tire mileage and probably better handling, too.

1700m (not a misprint?)and the tires are gone? both of them?
i would:
1. check the tire pressure gauge. especially if its the only one used on the bike. check it against other gauges and on other tires. its easy and eliminates that part of the guesswork.
2. get the wheels off the ground and hand-spin them to check for drag.
3. apply the brakes and release. check for wheel drag due to brakes not releasing.
3a.check for bulges and tread warp. broken cords may aggravate wear.
4. take some pics and document whatever you might find. never give the tires to anyone without a reciept with serial numbers listed. are the tires that are on the bike actually correct for the bike? i have seen tires from the factory mounted backwards and beads not seated.
5. are they mounted correctly and seated on the wheels like they should be?
6. two years and 1750m, hmmmm? bike parked in a tire eating enviroment? cleaned with some sort of solvent thats corrosive to the rubber?
if you ever find out, let us know. the difference between 33psi and 36psi in front wheel 'feel' ought to be nearly undetectable on the street. if the bike felt difficult to turn at one pressure and now turns "easily" at another pressure, the gauge might be sticking in a narrow part of its range. closely re-examine every step of your pressure checking routine. you might be bumping the gauge inadvertantly.
