Motorcycles + Two-strokes + IOMTT talk

Recommended Posts

The first ever motorcycle I fell in love with was a brand new Rothmans Honda NSR250R standing right next to my new MBX50 at Rupert's Bike Inn. Was thinking about it the other day and started thinking how to get my hands on one....it's nearly impossible. Searching the internet you realise how sort after it is and what you will pay for any make or model two-stroke motorcycle in good condition. I see they still love racing them at North West 200 road race in Ireland.

 

The Morecambe Missile John McGuinness who has won 23 TT's thus far, won his fisrt TT in the Lightweight 250cc class back in 1999 on a Honda NSR250 at the Isle of Man.

 

So, here's a thread to discuss everything two-stroke motorcycles; the technology, racing, history, videos, pics, etc.

I owned at one stage a Suzuki RG250 twin, watercooled, wickedly fast.

 

When I was growing up the Kawasaki KH and Suzuki GT two stroke triples were the hot bikes.

 

The sound of there 3 into 1 or 3 seperate expansion pipes was out to this world.

 

Would still like to own one today - the smell of two stroke oil is brilliant !!

A friend of mine had the NSR 250R in Repsol colours. That thing was crazy fast but could not catch another friends RGV 250.

those things were seriously fast to us riding DTs and RZs

Mate of mine had a Kawa KR250

 

That thing used to embarrass people on RGV's :)

If memory serves me right the NSR had a number like 64 or 18 or something that were bikes that came off the track or was just faster than the rest

I just love the feeling of the "power-band", a while back I rebuilt a Bennelli Jarno 125cc, seriously fast for a 125, just love it and miss my 50cc sup-up days.

Interesting, found NSR-World to be very insightful explaining the history, haven't read everything yet http://nsr-world.com/history/
