dont you need about 40 bhp for that unless its a cutdown with fairing ?
It would be interesting to see... One thin is for certain, it wont hang around!

Quite a few people have run 100mph+ lammies in the past - I don't know why it is treated as such a revered figure, it's only 1% scarier than doing 99mph :)

But I think Shocky's right, stock scooters with full legshields are pretty un-aerodynamic so you need a lot more power - maybe 20% more to do the last 5mph

Sticky, Do i remember rightly that your road test of the RB250 (over geared I think u reported at the time) was a couple of MPH short of the 'magical 100' figure?

So perhaps a purpose designed/more recent exhaust and the 5 speed box could make up that little difference for the reverential 100MPH club evangelists?

I think you'll find there's PLENTY of idiots around!!
The kind of idiot who is going to purchase it regardless of cost! There is only a limited amount of these being produced.
Affordability may be the question for many, desirability will be the question for the few.

Seems the idiots are in the few then!!

No firm purchase price on this yet, so I was informed today.

The RB250 building with a 5 speed box will be road going but not rally going, I'm really aiming to go sprinting here in the US ( I'm an Expat!).

What's the highest BHP the standard 5 Cyclone gearbox has gone up to?

The box seems well built. I guess that partly the design of a Lambretta gearbox area doesn't help the gears as motorbike gears can be the same size and even thinner?

bit p155 poor on the supply side, yes 150 boxes were delivered to the uk this week but there were only 90 sliding dogs/selectors so although i've paid for my gearbox and optional 5th gear i cant have my gearbox because it aint complete!
very frustrating considering i've paid for it all
