Stan Stephens Two Stroke Website
AN INTRODUCTION TO US
After over 40 years of tuning and rebuilding two stroke engines, I have decided to cut down the amount of work that I take on and to drop some of the services that I offer.
I will continue tuning. Rebuilding cranks, reboring barrels and rebuilding engines.
I am going to expand the "Classic" Engine rebuilding and engine restoration side of my work, which I have found a real passion for.
On the General page I have made suggestions of people I recommend to carry out the services I have decided to drop.
Nicosil Replating
In future, other than for engines I am rebuilding, I will not be offering a Nicosil replating service. See Nicosil page and General page for more details.
Moto X & Karts
I am no longer carrying out MX Bigbores and engine tuning or kart tuning. See General page for info.
RGV/RS250
After many hundreds of 300cc conversions, I have decided not to do any more, but I have organised someone to carry on the 300cc spares and exchange service. See General page for info.
UK Only
Apologies to our overseas customers but with so much paperwork involved with customs and excise, in future we will operate as UK only.
"Hopefully these cutbacks will enable us to enjoy some free time off. I think we have earned it."
Yours
Stan and Julie

Stan Stephens is the most famous name in two-stroke tuning but don't just take our word for it, we will let two of the most influential journalists in the motorcycle trade do the introductions!

"Stan Stephens is one of the most respected and effective technicians working in the field of motorcycle engine development. When I joined the M.C.N 20 years ago, Stans name was already legendary, he was one of the top two-stroke tuners,able to achieve performance gains without making an engine too fragile. Stan is recognised as the "Guru" of bike technology and he is always willing to share his knowledge with journalists like myself who need to get to grips with a technical problem. All Stans work is tried and tested on the dyno. Many tuners without the skill and integrity of Stan Stephens have quickly gone bust, but this man has shown he is here to stay and his customers value that assurance."

"Stan Stephens is one of the UK's best known engine tuners and has been in the business for over 30 years. He built his reputation on race bikes and for a long time has been synonymous with two strokes. Performance Bikes is the UK's largest-selling monthly magazine. Since the magazines inception in 1985 we have regularly tested bikes developed by Stan and his specialist team of engine builders and have used his excellent facilities to build project bikes for magazine features".
