Sport Classic wheels on a 620

[ollie]

I'm after a set of my spoked wheels for my 620, Has anyone tried fitting a set off a sport classic? I suspect that they will be too wide and possibly rub on the swing arm - has anyone first hand experience?

[Slide Panda]

The rear is wider - so you'd have to deal with that. People have done the 4.5" to 5.5" converson on the smaller monsters before - but its costly. Also, you'd be losing performance - The spoke wheels weigh a lot. The front is probably heavier that your stock one and the rear must be. So you're going to pay a lot for a slower to accelerate, harder to stop, less agile bike...

Ok Thanks, I thought that I had read somewhere that the spoked wheels were significantly lighter . I Wouldn't be Interested in doing it if it was going to add weight

[Slide Panda]

I haven't seen numbers... but as a general rule, spokes are always heavy wheels. Add the weight of an inner tube to the mix as well. Oh yeah... you'd need inner tubes...

The sport classic Rear with tube, sprocket and rotor tips the scales at 30.5 pounds the front at 17.75

3 spokes - wheel only goes for  11.5 lbs front, 13 lbs rear. Add in the rotors and such and you'd still be adding about 15 pounds of rotating, un-sprung mass to your bike.

Spoke wheels..heavy!

But..they looked good on the monsters I've seen in the past.  Mainly Euro bikes. Not sure I've seen any bikes in here or TOB with them?

Alpina wheels = no inner tubes.

Yeah - folks to make tubeless spokes - but he specifically mentioned Sport Classic wheels. Guess  I could/should have mentioend the tubeless... but they are still heavy by comparison

[Buckethead]

but they are still heavy by comparison

And relatively spendy.

Seriously, tho, SC wheels are RETARDED heavy. Can't wait to swap mine for a set of 10 spokes.

I thought the aluminum rimmed SC rims weighed the same as the stock 3 spoke wheels on the Monsters.  The GT1000's rims are chromed steel and are obviously heavier than those on the other Sport Classics.

I wish there was a chart that could show the actual weights (not just the advertised weight) of all the Ducati stock wheels and common aftermarket wheels.  Everything would have to be equal.  Advertised weights of all the aftermarket wheels are very optimistic compared to actual weights.

What year 620 does the original poster have?  If he has the larger 4-piston goldline brakes, then these will not work with SC wheels.  If he has a 2005+ 620 then most likely he has the 2 piston smaller brakes (same as those on the SC's) and these will work with the SC wheels. 

[Slide Panda]

That's not 100% correct. IF he as the 4 piston calipers, he would need the 320mm, 10 mm offset rotors vs the 300mm 0 offset rotors seen on the tail end 620s 695s etc... The wheels would work fine though.

here's where I got my info on the SC wheels

They actually weighed theirs. Then compared them to a set of Carrozzeria Forged.

Good to know that the change would only necessitate a rotor change for the later 620s & 695.

Thanks for the link.  I remember that article which I read when researching new wheels a while back.  Just like the author I opted for Carrozzerias from DucPond.  I too weighed my wheels before and after.  The stock front 3-spoke Monster wheel from my 2005 1000 weighed 10 lbs w/o the rotor.  The stock rear weighed in at just under 18lbs w/o the rotor or sprocket.  So those GT100 wheels are definitely a lot heavier than stock 3-spoke Monster wheels.  Looks like he would add 7.25lbs to the front wheel alone by doing the switch.  

I would still like to see the weights of the Alpinas and also the aluminum-rimmed SC1000 and Paul Smart SC wheels.

I've got an 05, It's good to know that it will fit with just a rotor change. I'd agree that it would be good to see some accurate weight comparisons between some of the wheel options, as it sounds that official quoted figures often vary a bit from actual rates.

Incidently, the wheels that I was considering were off a Paul Smart model, didn't realise that they were aluminium rimed - so I would be interested if anyone knows what they actually weigh

[Travman]

Since you have an 05 then you don't even have to worry about the rotor change since you already have the same 300mm 0mm offset rotors found on all of the Sport Classics. 

Now you just need to find out how much the aluminum Paul Smart wheels weigh.  If they are close to the steel rimmed GT1000 rims then I'd say no way.  If they are close in weight to your stock wheels then go for it. 

AFAIK your stock 3-spoke wheels weigh the same as the ones on my 05 Monster mentioned above.  I've got pictures of them sitting on the scale w/o rotors or sprocket for the rear.  10 lbs for the front and just under 18lbs for the rear.
