Hi guys---I had a CB750-K6 a while back and have to agree re}---handling. I think that in their day----like one or two others----it was a case of the engine's power outclassing the current rolling frame technology...Hence the "improved" frames from private sources...Also a decent fork brace will help... I'm in the process of putting a CB750 HONDAMATIC back on the road for next Summer---now THAT should be VERY interesting on quite a few levels ?? A "Twist & Go" @ 100 mph ?? A/L EDDIE--- Yes, the Barum's do have a reputation for a softer side wall---maybe a few Lbs extra pressure might help PLUS drop the rear shocks pre-setting down a notch to take some of the loading from the tyre ??

Hey Alan and Eddie - mine was a K2 (you know the gold one with four pipes). The wobbling was really strange - it would wobble at 40mph, again at 80, and was starting again towards 120 if I'd let it get that far (although it was about all done and dusted at that point). I never got to the bottom of it despite clip on bars, steering damper and a variety of different tyres including TT100s. I sold it in the end for a Ducati GT750 which although it handled was otherwise a complete bag of crap (probably worth a fortune though if I still had it).

I have a pair of 82 dohc F2's and I have never found or heard of handling issues with them. Honda must have sorted the problems by 82

I have identical tyres, 3.50 x 19, both front and rear on my Redditch Bullet. Yes it did slow down the handling a bit, but I don't find this a problem, she just needs a slightly firmer hand on the controls. Having the same size front and rear makes it much easier to set up the wheel alignment and also I can put half-worn-out front tyres on the rear, which avoids having to throw away "out of date" tyres which still have plenty of tread.
Yes the Mitas tyres do have fairly soft sidewalls, I run about 20 or 22 PSI in the front and 26 to 28 in the rear. Interestingly though the actual bead is almost as hard to tease on/off a rim as a SkidMaster, certainly much harder that a TT100. The TT100's can be fitted with thumb-pressure alone once you know just the correct angles required, and use plenty of lubricant, there is no way you can do this with the H02 tyre. Using three sturdy tyre-levers will make it a simple job.

Hi guys & HOWARD 612 ---- On my other Bullet (AKA No.2 Bullet) I have just fitted a 3.25 x 19 Mitas for the moment ( I have several spare wheels for front & rear so can try different combinations.)and you're right---they do have a v. tough bead. In the day we all used Barum (Mitas) tyres for Grass Tracking --- 23 x 2.50 fronts and 4.00 x 18 at the back I think it was. They were swines to fit as well but responded positively to the use of either tyre "soap" or Swarfega, thinly applied. Thanks also for the pressure settings---that's always good to know.

Just another small comment. I've recently fitted a new 3.50x19 Avon SM Mk2 to the front of my 2000 Bullet 500 (I've put a sidecar on it) and I found that some of the set screws holding the mudguard stays to the mudguard foul the tyre. It was easy to cure this, though, by reversing the screws so that their heads are on the inside.
