I found 22 to max.of 23 psi for our KLE(2006) for the front tyre best suitable for all the conditions we ride in.
At around 6.000ks we got rid of both original tyres, and replaced them with Michelin Sirac. Not looking back. Very good tyres, suit 80% road use and 20% unsealed road use. Longer lasting and not only better in the dry, but also better in wet conditions (sealed road).
I found if you put more pressure in the front one, it can loose a bit of grip while cornering if road surface is not spot on, so to say on the rough side.
Best thing to do with the KLE is to spend a couple of $ and get her progressive fork springs (eg.Wilbers Racing), in combination with the Michelins very hard to beat and a very cheap solution to make it a safer bike. The bike's ride becomes more predictable, more direct.
