1: Our panel said…
…well, nothing actually because the panels in this case are side panels for CZ Mxers. Cast your mind back to our cover bike last issue, John Fleming’s CZ, it bristled with special bits and pieces including superb aluminium side panels made by Norrie Pattie’s fabricator at 3L Road and Race. They’re designed to fit the frame used in John’s bike and complement the airbox we featured last issue.
What are they?: Sidepanels for a CZ Mxer just like John Fleming’s. Where d’you get them? They’re from 3L Road and Race on 07980 290898
2: Gear selector
One issue CZS have is the length of travel on the gear lever when trying to swap cogs. It can be a bit inconvenient to say the least in the cut and thrust of an MX race. While a bolt-on linkage system shortens the travel, Norrie at 3L does a modification to the internal gear selector which, allied with an external linkage, brings the gear change into the realms of equivalent Japanese machines. Saves missed gears, damaged 'boxes and lost races.
What is it? It’s a CZ gear selector mod.

4: Nicely contained
Petrol tanks get damaged in off-road sport. It is a known fact, drop the bike and the tank is dented, a bit of high frequency vibration and the seams will split too. Yes, they can be repaired, but it might be just as quick to fit a new one. These smart polished alloy ones are available through 3L Road and Race. Want to know if they’ll fit your CZ? See Norrie Pattie.
What is it? It is a newly-made aluminium tank for CZS.

3: Exhaustive testing
A lot of two-stroke engine prepping involves stopping air or gas from entering or exiting where it shouldn’t. The more closely the gasses flow to the ideal drawn by the designer, the better the engine will work. For most of us it is a case of following the manual and doing what the factory suggest to ensure the seals and whatnot are as close to the instructions in the handbook. There are of course those who can make alterations and improvements to keeping the gas flow going the way it should and a CZ exhaust port is one such area. After years of use heating up and cooling down the cast an adaptor doesn’t seal as well as it should. This mod sorts all that by modifying the barrel and allowing the previously fixed tube to be replaced.
What is it? It’s a CZ exhaust port stub mod to help exhaust sealing. Where d’you get them? They’re from 3L Road and Race on 07980 290898
5: Top hat
In our world, sometimes a modern helmet just doesn’t look quite right, but the advantages of modern technology can’t be denied… so along comes a helmet built to old school style but using modern technology. The LS2 Bob Carbon is constructed from a carbon fibre shell, by LS2 themselves, with three sizes of base shell to provide the best fit possible for an individual.
The liner is breathable and hypoallergenic so should remain comfortable in extreme conditions, there’s a retaining clip for goggles, a peak can be attached and there’s an option of a clear visor if that’s your thing.
It’s produced in Henry Ford’s favourite colour though we’re assured it is compatible with professional paint used by professional helmet painters and probably graphics too. It’s held on by a ‘D’ ring fastener, weighs in at 850g so is reasonably light and is available from your LS2 Stockist.
What is it?: It’s an open face carbon fibre helmet which meets ECE 22.05 spec, from LS2.
What’s it cost?: Available in sizes XS-XXL (53-64 cm) and retails at £199.99.
Where d’you get one?: Visit www.ls2helmets.com to find your local stockist.
6: Fancy footwork
In the old days, several tons of forged iron was fabricated into a massive bar to give riders' feet somewhere to be during those times when they weren’t helping a bike round a corner. These massive lugs were looked at critically and if there was any danger of them possibly being too light extra weight was added… then a bit more for good measure until the resultant part could be used to plough furrows in fields and plant crops…er… well not exactly but you get my drift. Footrests were massive things and everyone thought they needed to be to do the job, if they got bent then the local blacksmith would heat them up and reshape them. Then a different idea came in, I think it was Andy Roberton who pioneered the use of spring-loaded footrests on Mxers in the Sixties… all of a sudden bikes were tons lighter, footrests didn’t bend, the sun still came up and… well, these rests are for a CZ, well made and light.
What are they? Footrests, wider, lighter, nicer.

7: Forking out
Fork yokes are those bits connecting the frame at the steering head to the fork stanchions, in the USA they can be referred to as ‘triple clamps’ but yokes do it for us. They keep the forks at the correct angle in relation to the frame and the correct position in relation to the track. In the past they’ve been made from steel forgings, steel castings, aluminium castings and so on. Problem is, especially on dirt bikes, they can twist or bend or come out of true after years of use. Add in technical thinking on trail and rake has changed over years of time and maybe there’s a better idea out there. Audit CNC Ltd have been making a selection of yokes for various bikes – pictured are sets for Bultaco Sherpas, TLR and RTL Hondas and Fantic – and this is their latest batch. Ossy at Audit CNC Ltd says they can make yokes for almost any bike and are happy to discuss specials if what you want isn’t out there.
What are they?: A selection of fork yokes for various trials bikes. Where do I get a set?: From Audit CNC Ltd sales@auditcnc.com 0191 371 8888
What’s the cost?: Depends on your spec, call or email them
