Thats the 5 geared RD 250A your engine is probably out of a post 75 bike ( unless someone removed blanking plate for 6th gear ) mine was RD250B good fun in the day certainly kept up with KH's and GT's at that time all seemed on par speed wise

Well that`s our 13th year & still loving it.
My father bought a Yamaha Rd 350 in 1973, couldn`t believe the power it had, it was difficult to keep the front wheel on the ground, had the have the rear wheel rebuilt.
Fantastic machine.

In the 60's I rescued a Sun from a locals old guys shed, it had a 250 twin villiers engine and it frightened me it was so quick and the brakes were useless, it was the same as this

Fantastic machine.

Bit like my RD 400E, first and second gear and the front is up once the powerband comes in.
Makes for interesting riding when it happens being cranked over going around a corner!

I have had a Triumph t140 for over 20 years. Great bike. Last year I fancied a two stroke so I bought a Suzuki gt 250. Both 1975. Completely different bike to ride. Nothing below 4000rpm but it puts a smile on my face.
Can't wait for the spring.
Which one shall I ride first?

The one that doesn't have both pistons at the top at the same time :D.

The day I took the photo, my son came for a ride. He'd never ridden a British bike before . We swapped bikes along the way. He's owned two strokes and Japanese four strokes. He couldn't believe the torque in the triumph but preferred the Suzuki.

Spent a bit of time, setting the timing on the Suzuki. So I know which one you mean.

Gt 250, handled like a bag of poo,good in straight line...kick start on the left..left good smoke trails when you gave her it. Great fun and learnt you how to ride.
Not as free reving as it’s competition, the RD250.
Looks great though:)

In terms of torque vs power output, if you compare size for size, you'll find that the 2-stroke has considerably more low down torque than the 4-stroke. Unfortunately, and it was particularly true back in the day, quick Japanese two-strokes were/are being compared with 650 parallel twin four-strokes.

Back around 1968 I had 2 bikes at the same time .... one for "fun" and one for "riding". Both very similar to these pics.
As many have said the smell of Castrol R was addictive :)
The Vello was my absolute favourite ride of all the bikes I have owned. Except when the sod "kicked back"

The very bike I learned to ride on, a Greece’s Scottish trials belonging to my BIL, but an earlier one with the Villiers 197cc engine and paddle hubs,

I meant Greeves trials, bloody predictive spelling.

I think it was methanol we used to nick from work, and stick some in the tank along with the petrol, no idea if it made any difference. :)
