    Everyone indeed has their own take on handling but there are a lot of good reasons why 99% of all bikes have smaller front tires than the rear and it isn't looks. I set my friends CRF450 up for a local short track/TT. I asked about the track and if there were any tire rules. He said you could run knobbies if you wanted. I left his 21" MX knobby on the front and put a flat track tire on the back. Some of his buddies saw the setup before Friday night and were telling him it wouldn't work. Come Friday night, ALL of those guys were behind him. He said that in just a few weeks depending on the track conditions most everybody was running the same setup. I don't think the knobby has any more grip on hard pack but I do think the profile and less weight of the knobby makes the bike turn and handle a LOT quicker. Later on my friend was short tracking practicing with Ben and Eric Bostrum. He told them the story and they both immediately said that they very often like to run the same setup IF the track will let them.

    In my experience, the bigger front tire you put on an airhead, the more they want to tank slap.

    I think if I made up one of those "scramblers", I'd have to put some of those factory style high pipes on it. They may not really be necessary and they will burn the hell out of things and make maintenence a PIA, but a scrambler just otta have some.

    I did the opposite - when we started racing bikes at our local car dirt track with hard pack clay,I took my TS400 down to use.I didn't like the 19in front wheel,and had fitted a TM front end from my dead donor TM400.The 21in knob was crap on the hard pack,and refitted the 19in into the TM forks,and fitted a 3.75 Kenda Speedway tyre,and a 4.00x18 trials tyre to the rear.This was a great set up,and tried it on some gravel roads too,and found it better there than the 21in too.Hence the reason my R65 is set up like that,and confirms my earlier findings.Each to their own.

    Very good point. As well you end up with 18" wheels front and rear, short wheel base and an alloy upper triple clamp.

    Most excellent Guzzitaco:clap
    I have a 74 R90 I'm modifying and I like a number of the builds- lots of great ideas. Keep them coming if you can!
    I'm still researching frame bracing, weight lowering, and a rear fender.
    I think the semi raised fender of a scrambler is practical and is distinctive.

    As far as the aesthetics go, a motorcycle is a toy we like to play with, therefore form or function is important most to the owner. I hate choppers, but there are some styling cues that an be practical too. Just love the diversity.

    Too bad BMW doesn't do some retro scrambler bikes a la Triumph.
    The old scramblers were pretty bad dirt bikes. Anything we make now could be a vast improvement just because the suspension and tire choices are so much better.

    and another...

    This is a R75 that was for sale on ebay in Germany. It got to 6,800 EURO and it didn't make reserve! :puke1

    It is supposed to be one of the prototype scramblers put together by BMW.

    They sometimes run flat track tires front and rear at the track I am talking about. Usually, about everyone agrees on what works better on that particular night. But what works better is comparing oranges and apples. If they made a smaller flat track front tire I am sure everybody would be running them soon enough just like they do in every other type of motorcycle racing out there. Including speedway racing. The only motorcycle racing that I can think of that runs as big of a front tire as the rear is flat track racing and that is because the rules make them. It's great that you like big front tires but most everybody else doesn't on street bikes and dirt bikes. Not if they want to win races. Big front tires certainly do slow down handling except for when they tank slap. They speed that up quite a bit. It's fine that you like them motu. I am just trying to help others set up a good handling bike by pointing out how it is.
