I think parallel twins are brilliant, but they're not 'sexy' like v-twins, are they? Marketing guff has a lot to answer for!

Anyone got a spare 500cc 2-smoke single kicking about? Or even 2 with a custom cranck and case, that would be a challenge.

I know a French guy put a RD500 engine in a 4DX

RD500 3tj???? About 100bhp?? And a possible 120kg?? that would be an experience! 0.8333 BHP/KG

The RD500 lump is still heavy though, the 350 would be better-

One day...

RS500 hhhhhmmmmmmm been there, thrashed that!!! Best machine i have ever had the pleasure to cock a leg over.

Ultimate 2 wheel, 2 stroke porn, if i had the money id buy one without hesitation and lifetime supply of Kleenex to go with it!!!!

The TRX lump may not be the best in the world but it's what I have and if I can get the TRX lump in the FZR and keep it to about 150KG it's going to be quite a bit better than what I'm using at the moment as it has the same power but weighs 175KG!!

On the note of 2 smokes I have heard tell of 2 CR500 barrels on a custom bottom end making a CR1000 V twin. I don't know any more that that but that has got to have been fun!!

I have weighed the TRX lump and it's about 75KG with carbs and oil.

If I could get what I wanted it would be a 1000cc parallel twin with a stacked box like the R1 / R6 nice and short light weight and plenty of punch!! But dreams don't power bikes....
....yet!!
