Comparison between G2 and B1 Royal enfield engines

Orignal G2 engines from England were last assembled up to 1968 in india. From 1971, Enfield bullets were built in India with B1 engines.

The new models being launched are having unit construction engines(uce), fuel injected and have a 5 speed.

If you get the original G2 Engine, that'll be great!!

Answered by Sameer on 07-06-2012

Initial B1 Engines were imported from England By Enfield India till 1976. They were G2 engines stamped as B1. The Redditch company shut down its manufacturing in 1970. There was plenty of supplies to be utilized till 1976. After 1976 Enfield India started manufacturing complete bikes on their own.

Hi all, I am a very proud owner of a Royal Enfield which was my dream bike from childhood and that too a 1973 vintage.. Its just amazing to ride makes one feel Royal.Would like to thank Mr Shailendra for giving the most sensible and factual explanation between G2 and B1. You wont imagine how eager i wanted to know and i was not satisfied until i read your response to Mr Ayyappa Das. Thank you ever so much... i always u to think why does the G2 and B1 engine look exactly the same and yet are different.. one mayor advantage is that G2 have brass bearings fitted..

Answered by Akshay.. on 04-10-2013

The G2 engine originally belong from England up to 1969 in India, after 1969 enfield india manufacture engine self in India and before 1970 madras company ( Enfield India) were purchase/ received form england. The last model of G2 engine's motorcycle in india was 1969. the most feature of G2 engine's is engine sound , in G2 engine timing gears were very silent then b1 engine , the G2 engines are performed good or slow RPM with the AMAL carburetors but mines point of AMAL carburetors was mileage that is only 20-25 km/hrs. but the best feature is firing which is about my experience i think 1 firing in 0.75 second and it is such mind blowing those you are calculate the firing of bullet in slow RPM.

Answered by Girish Kumar Suthar on 03-12-2013

Hi-guys, the feedbacks given by shailendra & Girish Kumar are true to the Core. I'm too a proud owner of G2 Engine bullet. But there has been certain difference in the engine structures at a same time of production. For eg.,the breather pipe from the engine is seen as molded model as well as 3 screw bolted model in same year. I wonder why this difference ? the rest of all species are the same. Also guys there is a major structural difference in the swing arm connecting portion of the old bullets mainly 1950-1956 yr. This is told to be produced in the former factory of Bullet @ Brad Avon which was shut down before 1961.

hi guyz i have 1969 model b1 can anybdy plz tell me abt whthr it is made in england or not??

Answered by Amod on 03-09-2014

Pre 1968 all number started G2, + had EI number as well. Engine and frame numbers matched when left factory.
From 1969 eng numbers started B the the actual serial number xxxxx / followed by a single number: 9 = 1969, 1 = 1971 etc and then a letter that denotes the month. This continued until 1982 when the number sequence changed again, B followed by the 'year' code letter, then serial number XXXXXX.
Last English made G2 supplied to India was in 1964. ALL engines and gear box after 1964 were entirely of Indian assembly, made from local and imported parts.
Last parts supplied from England was the Con-rod, in 1976. From 1976 on the Bullet is entirely of Indian manufacture.

Answered by George on 08-09-2014

Answered by L G Munde on 01-08-2015

Hello all,
UK Royal Enfield Owners Club chairman here.
In the postings on this forum, there is an awful lot of rubbish regarding B1 engine numbers. It is true that the Enfield India factory changed from the UK style G2 prefix to B, but they NEVER stamped their engines B1.
If you do have an engine with a B1/ prefix, it will have been added by whoever restored the bike !!!
