Dunlops on a CB750?
« on: May 26, 2008, 07:34:34 PM »
So, I had Dunlop D404's on my Virago 750 a couple years back and I really liked them.  Rode through some very heavy rain, lots of different temps, etc.  Almost 8,000 miles in one year on that bike and the tires seemed to wear very well.  I need new tires for my CB750 (K1) and I was wondering if they'd work as well on that bike.  I seem to remember that someone posted that ires with diagonal grooves like the 404's (most modern tires, in fact) mess with the handling characteristics of the CB750.  Anyone care to comment?  The bike is bone stock, still has the loose balls in the steering and the bushings in the swingarm.  Is there a better choice for tires?  Don't care as much about maintaining "the look" so much as I want a good tire that grips decently well (not a corner carver, though) and wears well.  I ran Cheng Shins on my chopper all last year and they were fine too, but this bike is gonna see a lot of two-up riding with my fiance and I want it to be extra safe/reliable.

As a second note, the current tires are Dunlop TT's (I didn't choose them) and I never got to ride the bike on them.  The front is a 100/90-19 and the rear is a 110/90-18.  The front is pretty standard, but the rear seems narrow.  Would a 120/19-18 be a better choice?  Maybe even wider?

The Dunlops are ok with tubes too, right?

Dunno about the 404's I have 501's

No problem with the tubes and if you go 120 on the rear the center wears faster

Ive used Dunlop K491s (no longer availlable) on my CB750K4 - 16,000 miles on those. Now have the 501s and also pretty good. 12,000 miles on the last set. Hard wearing tire and a little harder than say Bridgetones BT45s.

cheers

I've got 404s on mine and am generally pleased.  Seems the grip in the wet could be better, but maybe that's just me.  They're certainly wearing well.

Do a search and you should pull up quite a few post about this specfic tire model.  I think it's come up before, they seem to be a pretty common tire.

I second the 404's. I can't speak to their real handling limitations as mine are generally reached long before the tires. ;)

I have them on two 750's. For the price I think they are a-ok.

I'm not sure how hard that are to get these days (I got my last set a few years back), but I've always thought the classic Conti Twins were the right tire for a K bike and they're available in the exact stock (inch) sizes.

I'm def. looking at these for the next tire change. When I got mine back on the road after 22 years and needed new tires, I recalled some not so fun instances in the 70's with ribbed a ribbed front tire on rain grooves and bridge gratings so I opted for the tread design on the D404's. Now that I've had it on the road for 3+ years again, I realize I don't ride anywhere where there's grooved pavement or bridge gratings so I will go for the "look" next time.

Yep, the ribbed tires are spooky on gratings and grooves.  I've always just ignored the jinking and let the bike have its way a bit, like a dirt bike, and it's been Okay.  Otherwise, ribbed tires are what the bike was designed for and actually give it nice handling.  Except for really bad stiction in the front forks, my K1 handles very sweetly.  And the bike looks correct with the ribbed tire and we all know that looks are everything.   ;)
