Dustin....Some 250/305's were "backwards"... The CB77 (305) even kicked forward on the left side .... :lol: :lol:
Left-side shift in a down for first, up to upshift pattern, and right-side brakes weren't standardized until 1974 -76 (somewhere in there)...... Before that, anything that worked was OK... My 63 90cc has a left shift, but its neutral at top, and down from there to upshift.......... My 66 Sprint has a left brake, and right shift.... Imagine getting off one and onto (trying to ride/riding) the other....LOL....

My first street bike was a 72 triumph with right side shift. As I rode away with the PO standing there watching I pulled in the clutch tried cram my foot under the brake to upshift and somehow managed to aply the brake skidding the rear tire I did pull it off without stalling it but still it was pure embarassment.

We used to switch back and forth all the time back in the day as well. I had a '69 Norton Commando S and would ride that on the street then switch over to our Yamaha dirt bike or my dad's CL350.

Nowadays we have a similar problem going from my race bike to the street bike. Our race bike use a GP shift pattern which is 1 up 5 down. I don't think about it much anymore other to remind myself when I get on the bike. I'll admit to having a brain fart once in a while and grabbing the wrong gear. We put a little stick on the triple that says 'GP Shift" to help remind us.

When I was sourcing new rubber for the 450 I was told by several local folk that I would considerably compromise performance and handling if I went to a larger front tyre. Now I see this little gem I wish I had done it...I love the look of the fat front end. Any comments?

Garry.... Tire size/application is a factor of a few parameters..... You won't hurt performance as long as the RIM WIDTH is proper for the size tire you run....However, mounting an grossly oversize tire on a "too narrow" rim CAN be detrimental.... The same applies for "too narrow" a tire on a wider rim..... Just like riding, the secret is "Balance"........ Matched size parts just "balance" each other and work together better...... The max width I'd go on a 1.60 rim is a 3.25 tire (maybe a 3.50).... A 1.85 rim can handle up to a 4.60 tire, but a 2.15 rim would be better.....

Steve, or anyone for that matter.

How do you determine those figures on tire width to rim width? Is there a formula for that? AT first it seamed that you were more or less doubling the rim width as being the tire width. But then a zinger of a 1.85 rim handling a 4.6 tire. Is rim width the outside width of the rim, or the inside width?

Ignorance is bliss, but I really dont have a clue! Strangely, I dont feel bliss, just stupid!

Henry, That is based on memory of what fit what.... I'm sure there is an actual formula for computing this........ Correction..!!!!! MY recommendation of the largest tire to mount on a 1.85 rim would be a 4.00" tire...Oops!..... (Pretend the previous was a typo)... :oops:
