I have rejoined the forum after a long absence. I had owned a TS 1200 but sold it some years ago as I found it too heavy. I also own a black SFC 1000 from new,one of the last batch of 50 wire wheels. I have had this in the shed for far too many years and it is approx. 3000 miles from new original except Jota silencers. I plan to recommission and register it now and use it a bit.
Any ideas on tyres, I have a local offer for Avon Roadrunner MK2. I did read Bridgstone RT45 but it seems it is a mix of RT45 and RT46 which I am reluctant to mix. I have also been offered Pirelli Sport Demon. Ant ideas here. I have quite a lot of recommissioning to do. Lockdown has given me time to think!
 
Hiya
        Tyres are a very subjective topic, one man's meat is another man's poison and all that tosh. All major manufacturers will make tyres for your bike and all will claim theirs are the best. The most important thing is that they are RECOMMENDED FITMENT for your bike. Use a decent reputable tyre shop and fit good quality tubes not cheap nasty rubbish. A good tyre shop will fit without damage, balance properly and check your wheel bearings whilst the wheel is on the dynamic balancer. Hopefully they'll even put them on the right way round. Search the internet on the tyre manufacturers websites and don't be tempted by cheap deals, you want new tyres not old stock. Personally I like Michelins and always have but I've got Metzelers on at the moment. Enjoy.
 
Best 18" tire I ever used on a Breganzie were the Rayon belted Perlli Phanton Radial (Super Comps) - Gotta remember Breganzie's came with Metzlers which melted off in one season.

120's on the back and 100's on the front (Perhaps 110's on the front) - SAD they don't make such a tire today for our 18" spoke Borrani rims ;o(

BT's or Avons will suffice. Always use a tube _ Dunlop make tires for our rides but ?

I have a riding buddy using Dunlops on his heavy 1300cc 81 Harley FXWG wide glide and he likes them but they don't tend to last more then 2 years at $200 per shot.

I ended up using BT's - 130 Back and 110 fronts - Satisfied NOT - Wish I had my Perrilli Phantoms ;o)
 
I used Pirelli, Avon, Dunlop and Metzeler at different times on my various RGS Corsa/SFC1000/RGS both on the road and track. However, The last tyre I bought for my hybrid RGS/SFC1000 was a Metzeler Lasertec.
 
When i was an apprentice, i was told dynamic balancing only worked on rims 4 inches wide and above.  Laverda wheels only need to be statically balanced.  If your tyre fitter is selling you super duper dynamic balancing, he is full of shit.
 
Hi Guys
              Did this "shit" for a living for fifteen years. A dynamic balancer simply means the wheel is rotated on a machine which electronically indicates where the weights are required and how much. As the wheel is spinning you can hear any stuffed bearings. Takes five minutes, costs pence. Paul, the guy's got wire wheels, tubes essential.
 
Not knocking you Bob, still doing this shit every day, if you can hear the bearing it is really stuffed!  I?m pretty deaf, rather trust my feeling. Put new tyres on Carlos wheels, bearing fell out on the floor, how did the last guy not notice this? Same guy fitted a heavy duty dirt bike tube, massively heavy and also the wrong size.
 
One of my rear wheel bearings did the same a while back, loctited it in but I have had issues doing that in the past. The bearing broke loose taking some of the hub with it. This was a Triumph years ago, I felt the bang and the wheel stopped mid-corner on Brown Mountain and then it went ok. 400ks later the whole centre of the hub flogged out. I noticed when the smoke started, the rear brake drum was acting as the wheel bearing. Apparently Greg in Melbourne has a lath big enough to fit a wheel and add a steel steave to fix this permanenty.
 
Dynamic balancing is also very reliant on the offset of the hub. Most motorcycle wheels have zero offset, so no need for dynamic. Although I do remember one iteration of Vince?s rear wheel modifications was actually offset. Looked very weird.
 
No worries mate. If you're still doing it you're well aware that some people are their own worst enemies. I could write a book on some of the disasters waiting to happen I've come across and had to go out to drag the bikes out of ditches after the owners have been taken to hospital. "Take your time to scrub your new tyres in, Sir. Just pretend it's raining for fifty miles". The record was a young guy on a Street Triple who lost it twenty yards from the shop. Flipped him over the bars, broke his leg and wrote the bike off. Spacers missing between the sprocket carrier bearing and wheel bearing was common. The wheel being loose is a bit of a giveaway, but what do we know? Bike specific wheel balancers are pretty good now, mate, and if you don't remove old weights first,,,, well, schoolboy error stuff. 
 
It may be true that dynamic balancing isn't necessary on narrower rims.  But it certainly is possible to successfully do so. 
And it does readily show up worn wheel bearings, not to mention bent wheels. Rather alarming how out of true some newer stuff is - like 1200GS wire wheels for example.
 
When I was attempting to fix the spokes in my rear wheel I visited someone in the bike buzz with a huge rep for fixing smashed bikes. He showed me a huge pile of GS BMW spoked wheels he was asked to fix for the local distributor. He had a long chat about them, and he knew the big secret not so well know. They have a tiny grub screw that is almost hidden near the nipple on the rim. Plenty said they needed to go back to the factory for repair as that grub screw didnt allow spoke movement unless removed.
 
Just for interest, the tyre fitters at Moto GP and WSB still balance wheels on static jigs. They are, however, highly skilled individuals with vast experience. Their work schedule over a race weekend is bordering on slave labour.

You're right, my mistake. Wire wheels.
