[09.0]

What's the deal with alloy rims in pre 60? Can I use them? Mud catchers?

They have to be mudcatchers

I will give it a run first and see if it messes with my head.

If you think about it too much it will f*ck you up. I've raced two different gear patterns at the same meeting with a rh Bultaco and lh Maico and Yamaha and a good mate regularly races three bikes with three different shift patterns. He reckons that after a while it all comes naturally, kinda like when before you go to the US you get all sweaty thinking about driving on the other side of the road but when you in fact do it it's  piece of piss easy.

Mudcatchers.....Akront, Borrani, and my personal favourite Takasago off early Japanese bikes. I'm using Borrani on my own pre 60 TriBSA.

Brad, back in the 90's I raced a 79 CCM in the then pre 80 series down here. I also raced my Mk7 360 with left foot gear change, 1 down four up, CCM had right foot change and 1 up two down. Being too old to comprehend it all in a panic situation I found it easier when braking was needed to jump on both sides, get set up entering the corner then change to the gear needed to exit the corner. Certainly not text book but worked well for me

I realised I have been riding a trike around the paddock which is all down. I'm over thinking it for sure. Right hand gear change on a 2 stroke does my head in as I had to sell the Monty GP I had for that reason.

Both Titmans and Ashes said they could get them in, not cheap though. I found some s/h ones to polish up

Correct me if I'm wrong, but in MOMs from years gone bye were not the only acceptable rims for the Pre-60 class steel ? Terry..

Here's a classic pre 60 bike that's been around the vintage scene since day one. The bike is the ex Hedley Gunter TriBSA that Hedley brought out when the family migrated from the UK. Terry, Adrian and later Anthony all learned the motocross trade on this old banger. When photographed at Nepean in '93 it was owned by Phil Barrett but it's now a part of the Edgar Phipps collection. He took it to CD9 and we're hoping he brings it to the Classic Nats in Canberra later in the year.

Will that be how you're hoping yours will finish up Firko? Very classic look to it

Tony the above TriBSA is built in the heavyweight traditional manner using a BSA Goldstar frame and 500cc pre unit Triumph motor, Norton forks, BSA wheels and Goldy Lyta alloy tank. I found this little C15 trials bike for sale on eBay a while ago and it planted the seed me that I might be able to build a slightly more butch scrambles version of it which would be potentially much lighter than the traditional TriBSA. The engine in the bike is a 350 but it proves the point that the unit Trumpy fits in the hole where the anemic little 250 once resided. I'm using a 1959 BSA C15/250 frame, 1959 Triumph T100 unit motor, Norton forks, BSA Goldstar front wheel, Harley Davidson Sportster rear wheel, Borrani mudcatcher rims, BSA B44GP tank and replica seat.....all pre 60 legal.
                                                                                        
If you can imagine the below bike with a Triumph 500 unit motor, that's pretty much what it'll hopefully look like.

A lot of these pre-60 bikes seem to wearing 35mm Ceriani front ends.






Does anyone know if the same Ceriani style in the 32mm size also legal for pre-60?

There shouldn`t be a problem, as it states in the GCR the commission and scrutineers will use the GCR components a guide line, In a nut shell, they don`t know, and they are guessing, and it will
depend on the person on the day, those forks look period, and the should be aloud to be used.
