Hi lads, just wondering if anyone knows the weight of the 2013 onwards 675R wheels. I was considering some magnesium or carbon ones but from what I'm reading the 13+ wheels are pretty light and well made.
I don't know the exact weight but I think forged alloy was only around 10% lighter, obviously mag and carbon will be lighter again, especially with lighter discs, however someone will be along shortly with a measured weight difference. Needless to say the gains are pretty slim
https://www.675.cc/675/threads/what-did-you-get-in-the-post-today.16920/page-119#post-414304 3.9 Kg in the front, 5.2 in the back
Yep and that 5.2 for the rear was without sprocket carrier by the looks of it, aftermarket wheels tend to also have lighter weight sprocket carriers and sprockets. Maybe another 0.3-5
I have a set of forged aluminium OZ wheels - when compared by hand the weight difference is not massive by any means. The distribution of weight however makes a nice improvement, the bike turns a bit better and spins up a little better also but nothing significant compared to what you would get with carbon. They look stunning though. Edit* I was told that OZ no longer produce wheels for the 13+ bikes as to make any improvements would mean the wheels would be to brittle - stock ones are very good.
Thanks lads, the more I'm reading the more I'm leaning towards stock as the only thing worth changing for is Magnesium or Carbon fibre. Marchesini do a very nice set of M7RR 7spoke Magnesium wheels. They quote 7.7kgs fitted. I wonder if I was changing the rear wheel would it be worth exploring the idea of a 6" rim?
I wouldn't put a 6inch rim in the bike personally, it will mean a 190tyre or the 180 will be stretched out of shape. That will marginally slow the steering which negates what u are trying to achieve. Maybe try 5.5 inch rim with a 180/60 profile tyre, all the supersport guys run a 60 now and that I believe gives a slightly fatter foot print at lean
Yes I agree, I was just throwing it out there to see if anyone had done it and if buying a new rear all available options should be explored. I've previously run a 180/60 and it does feel better at lean but is also heavier and slows the turn in a little. Dymag seem to be doing a good deal on the CA5 Carbon wheels. They weigh 2.2kg front and 4.75kg rear with sprocket. From what I understand the OEM wheels weigh 3.9/5.2 no discs or sprocket. I'm guessing the sprocket and carrier weigh at least 2kg which would bring the rear up to around 7.2kgs. That's 11.1kg OEM verses 6.95kgs, approximately 4.15kgs lighter with an additional rim mass advantage for around £2400.00 shipped. In an effort to save a few quid I was also toying with the idea of just buying the front wheel. Out of the two it would make the most difference and cost around £1000.00 shipped. I'm in the US with work for the summer so I'll keep looking but One thing I have confirmed during my research into aftermarket wheels is the OEM Triumph ones are on par with the best of the aluminium ones and the only way forward is Magnesium or Carbon fibre!
The reason I bought the extra pair of wheels was due to this and the result was this on the front, same on the back My guess is that carbon or magnesium aloy might be even more fragile than the OEM...
Jesus, that didn't look like a particularly bumpy curb? Light weight wheels will always be a compromise over strength. Ironically carbon fibre ones can actually take more of a beating than aluminium ones. Obviously the main difference is aluminium can be repaired/ straitened but not in your particular case. That wheel is proper Fooked!
