Bevel

RWG

Hi folk,

I have a project that I have started, with a Darmah that is going down the modern rolling chassis route,
I am fitting Online rsv front end and wish to carry theme on to rear and my question is does anyone know if the option for a larger swing arm exists that would allow 170 section or even 180.
I see a swing arm on EBay in Us, but is only upto 160
Any help would be apriciated.
Cheers
Paul

Trying to get tires might be an issue. But the question remains why you would want a 170? Hell there just isn't that much power to warrant a big fat tire. The other issue is space. I have one of those chrome moly wide ones and there is only about 10mm between the swing arm and the exh/rear foot peg frames.

How much rear tire width does the front sprocket location allow?

Mr.R

The gearbox sprocket can be reversed to gain an extra 2mm, using a different/wider spacer behind it would probably gain another 4mm. But you might need to modify/slim down the sprocket to stop running out of thread to hold it on?
The wider NCR type swinging arm can take a 160 tyre, roughly equivalent to the old 6" slicks of the day.
I run a 140 on my old Bevel it's more than enough tyre for me, this was the preferred "Proddy" race size back then, it's on a alloy rim 2 sizes wider than standard.
The 1st 70's 750/900SS had a 110, later '78 they had a 120 and IIRC? The Mille's had a 130.
Getting decent tyres in 18" could be a problem now.

Sorry should have said, I am aiming to fit 17" spoke wheels for sport classic range, I have a rear and looking for a front.
Got the idea from a magazine showing the V2 Australia take on a modern Imola rep, bevel. The motor has already been sorted and should be good as it was treated to a few goodies, carbs will also be sourced after recommendation from engine builder.

This might not be what you consider as help, but here goes. The bike I truly enjoyed riding the most over my last 58 or so years of riding was my lightly modified 1980 bevel ss. Those old bevel engines AND chassis make for a ride pretty much like nothing else. About all I did to mine was set the forks up properly with gold valves, put on good shocks, put on good brakes and a set of very light Marvic 18" three spoke magnesium wheels in 2 1/2" and 3 1/2" widths with decent tires to suit. I left the engine stock. The only bike I've owned that came close to being that great a ride was my 748/853. If I was doing those old forks now I would probably upgrade them with cartridges. So what I'm saying is, if you take away that bevel chassis, I don't think you'd have even half a bevel. That magic happens when they are working together, and you'll know when you get it right.

now that is a nicely set up bevel.i shouldve bought that when you were selling it

Mr.R

That's a nice looking updated Bevel Bill, how could you face selling it?
I still own my bought new in early '79 900SS and can't think of a situation where I'd ever consider selling it.
Only yesterday my ferry tickets for this years Classic TT/MGP arrived, my youngest daughter Ysella was over the moon when I showed them to her.
Daddies littlest girl going away for 10 days with her Dad on "Beverly".
She'll be well prepared with a bag of ear plugs, as my old nail runs full race open exhausts (to match the motor) that make Conti's sound positively quite.

Many years ago now I had Maxton sort out the front forks and run 1" longer Fournales rear shocks.
I've got "Period" 2 piston AP Lockheed race calipers front and back with floating discs on the front and a small early 750/900SS rear disc.

Even after all these years (38) it's still a hoot to ride, if I hadn't promised to take Ysella to the Manx, I'd be off to the Classic Bol D'or in September at Paul Ricard.
But I think it's a bit far on the back for a 12 and a bit year old girl, it would be at least a 2,000 mile round trip.
Still that's a solo plan for next year either on the old Bevel or my 955cc 851.

if you're looking for good (racing) tyres, try the continental ''classic attack'' tyres.
had them fitted to my Guzzi LM3 and raced it on zandvoort.
i was very impressed.

i used standard tyre sizes.

Thank you gentlemen, yes, that was a tough one to let go. I still have to remind myself about needing to pay off the race expense credit card and get out from under a stupido car loan co-sign.
