I too am finding it IS a real problem. Since I value nimbleness in my motorcycles, I am always looking for tires that not only offer high traction (for safety and confident handling), but also low weight. But for both my current bikes, my Yamaha R3 and my Z125, I am having trouble even FINDING the weights anywhere in the manufacturers' available specs. When I email them, I either get no answer at all, or I often get an answer that is clearly erroneous (e.g. a smaller front tire that the reply says weighs more than its matched larger rear tire). Sometimes I get told that the manufacturer makes a rear tire, but no matching front tire for that rear tire, which seems ridiculous.What size tires are people running in the front and rear? I'm having a hard time finding stock sizes without mixing brands.
I finally found a "mix" that would work, after reluctantly abandoning the stance of insisting on same brand and model of tire front and rear, and giving up on getting actual weights from tire manufacturers and depending instead on Dennis Kirk's website which has always been accurate to-date. I ordered:I know these might not fit your weight requirement but seems like the Kenda KD1 are available online at some places in stock sizes. I just went with 110/90 front and 130/70 rear Michelin City Grips. Pretty grippy so far but the spikes rub on the front fender (should go away after a while).
That 110/90 front is going to slow down your steering and also raise the front end visually and make it look "heavier".

That 110/90 front is going to slow down your steering and also raise the front end visually and make it look "heavier". Here's why:
A 110/90 tire has a nominal sidewall height of 110mm x 0.9 = 99mm.
The OEM tire has a nominal sidewall height of 100 x 0.9 = 90mm.
So, you are raising the front axle by 9mm = 9/25.4 = 0.35 inch!
You have already discovered that the extra 0.35 inch of sidewall height also raises the top of the tire to where it starts to get pretty close to the fender.
And the extra 0.35 inch x 2 = 0.7 inch increase in total DIAMETER makes that front tire look very tall and "heavier".
On the plus side, the bike will feel more "stable" at highway speed because of the altered rake.
Ah, very good, by installing a larger rear tire, You compensated for most of the height increase at the front,Yep I have noticed the steering change slightly. My rears also increased 7mm by going to 130/7 but it all seems to be a welcome change. Cornering is much better since my previous rear tire was basically squared off. Hope your tires work out!
Yeah, you're right if you want to stay with "matched' tires front and rear. I've given up on that and now trying to select the best tires separately for front and rear without doing anything drastically different between the two.Options without mix 'n matching. Kenda KD1 seems like the only reasonable option in a stock size... but those appear to be a more race oriented tire. It would be nice to have a good dual compound for street hooligan use.
