3. CLASSES.
Chassis
For all events the classes of machine eligible for the British Sidecar Championship is either F1 or
F2 chassis as specified in the FIM rules for F1 chassis and the TT rules for F2 class as laid
down for the 2020 TT (open class). In addition to conditions specified in the Engine Technical
Regulations contained later in these regulations. Suspension and exhaust components are free.

Engines
All engines will be restricted to four cylinder 600cc.
600cc engines for all outfits should comply with the specifications for engines in the 2021
Sidecar World Championships. (see section 15)

15. ENGINE TECHNICAL REGULATIONS – All 600cc Engines
(These are based on the FIM Sidecar World Championship Regulations)

Displacement capacities: 600 cc - 4 stroke only - 4 cylinders max
a) Motorcycles engines of mass production with an FIM homologation for Superstock
600 are allowed. All components must comply with the homologated engine, subject to
any statements to the contrary specified in the below regulations. The machining of
components, for example trough polishing, micro spraying or lightening is only authorised
if expressly permitted in the following.
The use of exotic materials such as ceramics, metal matrix or aluminium beryllium is not
allowed.
Parts can be omitted if not necessary for sidecar purpose.
b) The crankcase must remain as homologated.
c) Crankshaft and flywheel must remain as homologated. Balancing of the crankshaft is
allowed but only through the boreholes necessary for this purpose. No modifications to the
flywheel are permitted.
d) Connecting rods must remain as homologated.
e) Pistons, piston rings and piston pins must remain as homologated.
f) The original cylinder head must remain as homologated. The cylinder head gasket may
only be replaced
g) Valves, valve guides, valve seats, valve springs and valve spring retainers must remain as
homologated. Valve keys and upper valve spring retainers may be modified or replaced.
h) The carburettor or injection system must remain as homologated. Sensors and fuel
injectors must be standard parts of the homologated model, with the exception of
electronic and mechanical enrichment devices which may be removed. Intake bell mouths
may be removed or altered. Homologated variable length injection inlet track devices must
remain as homologated by the FIM. Inlet track devices may be removed.
i) Only standard camshafts as homologated may be used. No machining or kit parts will be
allowed. The Cam timing is free.
j) Chain, chain-tension and chain-guides may be modified or replaced. Belt tensioning
devices for belt drive systems are free.
k) Cam sprockets/wheels can be modified or replaced.
l) The engine control units (ECU) may be changed. Wiring harness, spark plugs, plus wires
and sockets may be replaced
m) Transmission/Gearbox: No modifications are permitted with the exception of shifting
components to invert gear selection. Pinions, chain sprockets, chain pitch and size may
be modified. The use of an ignition breaker and a shift indicator is permitted.
n) The clutch system type shall remain as originally produced by the manufacturer. Clutch
springs; friction and drive discs may be altered or replaced. Mechanical back torque
limiting capabilities are permitted. No electronic or electrical support is allowed.
o) Only standard generators for the homologated engine may be used. The generator must
supply the battery whilst the engine is running.
p) Electric starter shall be in place and work. The engine shall start on the grid with the
electric starter for the warm up lap before the start of the race.
q) Oil lubrication system is free. The oil sump and oil pump may be altered or replaced.
Installation of baffle plates is allowed.
r) The original water pump may be replaced.
s) Torque/Traction Control systems are permitted if fitted as standard on the homologated
motorcycle from which the engine is derived.

16. OIL & COOLANT REGULATIONS
(These are based on the latest FIM Sidecar World Championship Regulations)
Teams are reminded that due to the proximity of the Sidecar races to Superbike races on the
2021 programme that specific attention and care is required to ensure oil containment is a focus
of your bike maintenance and set-up. Track contamination during this part of the timetable must
be avoided to ensure the profile of British Sidecars is maintained.
In the event of oil or coolant contamination of the circuit the machine will undergo inspection by
the Technical Officials. If poor machine maintenance is viewed to be the primary cause of the
contamination then disciplinary action will be taken to include a fine to be paid alongside
subsequent event entry fees along with other sanctions.
a) In the area directly below the engine, the oil containment tray shall be constructed to hold,
in case of an engine breakdown the total oil and engine coolant capacity used in the
engine (min. 5 litres). It must be securely affixed to the chassis.
Please note: - the catch trays will be checked at Technical Inspection and must hold the
required 5 litres (when tested with water). They must also be of a robust nature fit for
racing. Any rider/machine found to be depositing oil on the circuit will be recalled to
Technical Inspection for checking. If the bike is found not to conform to the regulations
the rider will be excluded from the meeting.

b) The surrounding edges of the tray shall be at least 170 mm above the bottom of the tray.
Any passages for chain, chain tension device, gearshift linkage etc. must be sufficiently
closed with rubber sealing bellows or sealing lips to avoid any leakage of oil spray. Holes
for engine mounts (hangers) shall be sealed.
c) The frontal edge of the oil bay reservoir wall shall be extended upwards to arrive just
below (within 20 mm) the exhaust ports of the engine.
d) From a vertical view, the engine block shall be located completely inside the oil bay
platform.
e) The rear wheel shall be protected from any possible oil-spray. To make this protection, the
engine and the rear wheel compartment shall be separated.
– This separation shall be created by installing a solid divider (wall).
– This wall reaches from the top of the inside of the fairing and shall overlap the rear
edge of the oil tray to the rear section by at least 100 mm.
– An additional overlapping of at least 50 mm must be installed to the inside of the
catch tank in the area behind the cylinder head.
f) All sidecars shall attach oil absorbent materials of no less a quality than 3M Product
number 05656 or CEP Sorbents/ product numberCEP-EP100.
h) This material shall be securely fixed to the following areas of the sidecar:
a. The entire tray, both the bottom and inside walls of the same. The volume of
material used in this area, according to manufacturer’s specifications, shall absorb
not less than 3 litres of oil.
b. The material shall be attached in such a way that it should be easily replaced, yet
shall not become dislodged whilst on the track, and its effectiveness is not inhibited,
i.e. if an adhesive is used it shall not clog the material, causing it to lose its
absorbent properties.
c. In the event that oil is absorbed by the material, it shall bereplaced before the next
track session.
i) All absorbent material used, shall be non-flammable by design.

My god! am I glad I dont race anymore, why dont they just say, buy a standard 600cc 4cyl Jap solo & strap a sidecar to it. No wonder sidecar racing is dying on it's feet, where has the freedom gone?

It moved to NZ where we can run up to 1300cc and do whatever we damn well want to them

You want the richest guy to win?
Because that's how the richest guy wins.
Sidecars could easily be £100k with no regulations at all or even superbike spec engines which can be pricey.
