Cb500 weight 146kg

Post by l.t.racing on Thu 31 May 2018, 11:20 pm

Hi,  I have been building my self a cb500 race bike.  Dose any one know the std weight?.  See alot of diffrent reading online

I have got mine too 146.6kg wet but no fuel. Going to try get it in to the 145kg, which i have saved 250g since i last weighed it. Then it start on spending bigger money on trying to remove more weight.

 Thanks

Don't forget the tires, some brands/models weight more than others.

Where does it all end Lee,
Magnesium or carbon fibre wheels perhaps.
The downside that I have with mine is that I'm 10kg heavier than I need to be, and it doesn't seem to be disappearing very quickly despite my best efforts.

The cheapest option. Most people don't even consider losing weight themselves! These days, many can stand to lose multiple kilos.

27kg that's impressive!

I think that to loose 10kg I might have to hack a leg off or something similar  Laughing

Well, I'm fairly large to start with, I was 140 kg. however the basic method was to cut out alcohol, pies and sugar.

And here's me trying to get down from 80 to 70kg, the struggle is real Very Happy
As it's all about a power to weight ratio on the track, so I decided that I could either get down to Danni Pedrosa's weight or I need more power!
This is probably why I'm upping the power output, it seems more acheivable whilst retaining all my limbs.
The cost of a power upgrade also means having too many pies, sweets or beers is no longer affordable so it should be a win win situation although the scales tell a different story. confused

Well, it only got back on the road today after being SORned for a few months while I did a few titivations (new chain, some paintwork, wheel bearings etc) and I find that it hasn't got any quicker at all, unfortunately. 10,300 in top and it hits the rev limiter just as it used to do. What can I do to fix this ?  pirat

Look on the bright side, it still hits the rev limiter.
The question is does it get there any faster than it used to?
I normally gear bikes so that they only just hit the red line in top gear. Otherwise you're wasting power.
Try either a larger front sprocket or a smaller rear sprocket, or indeed a shorter piece of road to test it on.

Sprockets are far too technical for me. I think I'll try this technique

Wornsprockets, would that be a dig at me? If you want too know the true info. And I have heard it from the bloke I did the loom for. The bike didnt catch fire and it was not even a bit I would have touched. A wire fitting came out of the switch  gear side of the loom. Which I don' touch apart from remove wires that no longer used.   Ya he builds and sells good race bikes. I know of two bikes that brakes failed  on. One lad when straight in too a wall. Amount of problems I have heard about his work or bikes sold is unreal . But the people don' like to say owt. As they then will be a out sider.   I'm doing a engine now for a ts500 rider. Who is mates with josh but he said josh is a good lad but would not let him near his bike. What' that say then when its a mate

No not a dig in anyway i had electrical connection melt on bike from previous owner bodge ,  your bikes look good.  stuff coming loose parts fail thats part of racing, pushing bikes to limit these things happen. Sure i saw late great joey dunlop at skerries and his exhaust came loose on his rs250... who he blame... himself.??
