The Manx Grand Prix motorcycle races are held on the Isle of Man TT Course (or 'Mountain Circuit') every year for a two-week period, usually spanning the end of August and early September. New for 2022 is a period reduction from 14 to 9 days. 2023 saw the 100th Anniversary of the event where the Manx Motorcycle club did very little in the way of a celebratory program.
The MGP or Manx (as it is more commonly known) is considered to be the amateur rider's alternative and a learning experience for the Isle of Man TT races held in May/June. The event differs from the TT in that it does not cater for sidecars. A 'Classic TT' race category for historic racing machines was added in 2013 as part of the Manx Government Department of Economic Development's expansion to create what is termed Festival of Motorcycling to breath new life into an event that is costing the taxpayer millions of pounds instead of generating revenue for the island. These new races also allowed for professional and experienced riders to compete.
The event consists of six four-lap races of the circuit which begins at the TT Grandstand in Douglas, the island's capital. The separate classes are the Newcomers Class, Lightweight/Ultra Lightweight Class, Junior Class, Senior Class and the Junior/Lightweight and Senior Classic races for older machines ('Classics').
History
The MGP began in 1923 as the 'Manx Amateur Road Races' or MARC. The MARC continued until 1930 when renamed as the Manx Grand Prix. Problems were encountered initially over the definition of an 'Amateur' and the first rules were extensive and open to various interpretations. Nowadays, many riders who have achieved success in the MGP move on to race in the TT but regulations prevent them from re-entering 'The Manx' unless they wish to do so on Classic machinery. Chris Palmer (former British 125cc champion) and the late Richard Britton both followed this route in 2005 aboard Manx Nortons.
In 1989 Gloria Clark became the first woman to race in the MGP. In 1991 she gained an entry into the Guinness Book Of Records for being the fastest lady on the TT Circuit. Carolynn Sells was entered into the Guinness World Records as the first female winner on the Snaefell Mountain Course of the Ultra-Lightweight event at the 2009 Manx Grand Prix.
The MGP is organised by the Manx Motor Cycle Club (MMCC) based on the rules and regulations of the Auto-Cycle Union (ACU) which governs most British motorcycle events.
Classes
The Newcomers class caters for riders who have no previous experience of the Mountain Circuit. Such a class does not feature in the programme of the TT and is thus the only opportunity for newcomers to race the circuit in competition. Classes are usually over-subscribed as a result. Riders are limited to machinery with a capacity not exceeding 750cc and must wear coloured bibs over their leathers during 'Practice' (see below). Newcomers are also permitted to submit an application for any of the other classes but may or may not be granted a ride depending on their levels of experience.
The Lightweight/Ultra Lightweight class is represented by machinery of 125cc, 250cc and 400cc capacity. This class featured at the TT until 2004 but is now defunct and so, like the Newcomers' class, is extremely popular. 'Lightweight' refers to the 250cc 2-stroke machines whilst Ultra-Lightweight is the 125 2-strokes and 400cc 4-stroke bikes. This class is run as two separate races on Race Days (see below) but all the machines leave the start line in the same 'Session' (see below)The Manx Grand Prix Ultra Lightweight class lap record is still held by a Yamaha fzr 400. 109.86.mph Still held by Keith Taylor. This was before tuned mini twins were made eligible.
The Junior Class features machines whose capacity must not exceed 750cc. Machines of any engine capacity between 200 and 750cc are permitted but the vast majority of entrants opt to race four-stroke 4-cylinder 600cc bikes. Some 2-stroke 250cc machines are entered and there is a separate award for the highest-placed 2-stroke finisher (see 'Awards' below.)
The Senior Class is the final race of MGP fortnight and allows for motorcycles with an engine capacity not exceeding 1000cc. Again 600cc bikes are more popular than any other but a number of 750s are sprinkled in the start list.
The Senior Classic race features the most diverse range of marques and is very popular, with a full quota of 105 entrants accepted in 2005. Entrants must field a machine with an engine capacity between 350 and 500cc. Most riders choose machines with a capacity of between 450 and 500cc and common marques include Norton, Honda, Seeley and Matchless with the odd BSA and Ducati.
