Title: I think I've solved the puzzle..... Post by zipidachimp on 02/15/18 at 21:13:35 of why my attempts at a custom S40 have looked less than satisfactory. to wit: on the stock bike, the front axle centreline sits 13" above ground, while the rear axle sits 11.9" above ground, a rearward tilt of 1.1", exactly the opposite of what a good looking bike is. Through changes in rim diameter and tire size, I will level out the axle centrelines, at which point I can decide how aggressive I want the stance to be, longer rear shock, or lowering the front with a RYCA top tree and pushing the fork tubes up. At that point, I'll decide on a tracker, cafe or standard bike. Open to comments...... 8-) |

Title: Re: I think I've solved the puzzle..... Post by batman on 02/16/18 at 16:40:01 Expecting to raise the bike by changing to larger rims can be a bit deceiving ,most of the rims are narrower as are the tires that fit them, sidewall height is a percentage of tire width ,so a skinny tire has less sidewall height ,when added to the larger rim it may only be slightly taller than your stock tire and rim . you should check the diameters of the tires you will use before spending money on larger rims . a good site to compare is at -Tacomaworld.com- scroll down the left side of the page and you'll find-Tire size calculator - which allows side by side comparisons with lots of info. |

Title: Re: I think I've solved the puzzle..... Post by zipidachimp on 02/16/18 at 21:43:00 I discovered tacoma world a few years ago. I've also spent time comparing a lot of different bikes and the stock tire sizes the oems used. I wouldn't be doing any of this if my current rear tire size of 140/90-15 didn't look so goofy and my steering didn't feel so slow. At this point I'm leaning towards 100/90-18F and 130/70-18R. I'll change the rear first with the stock shock length, try it and go from there. 8-) |

Title: Re: I think I've solved the puzzle..... Post by batman on 02/16/18 at 23:08:55 Good, but you might look at the 130/90/15 for the rear ,that might allow as fast a turn in as the 130/70 /18. and you could go to a 90/90/19 on the front for the same reason. taller shocks will also decrease the neck angle , I run 13" progressive's myself. but it's your bike ,do what pleases you. good luck! |

Title: Re: I think I've solved the puzzle..... Post by Ruttly on 02/16/18 at 23:53:18 I like the 18s front and rear on the tracker. Looks are good and it turns just fine. I think 17s would look funny and not improve turning all that much. |

Be sure to use rims of the proper width to match the tire you intend to use. Vintage style tires with numbers like 3.50-18 are generally designed to fit on the narrow rims that were used......while modern tirs with numbers like 130/70-18 are made for use on wider rims. If you squeeze a modern tire on a narrow rim the cross section profile of the tread is made rounder, and a portion of the tread is rolled over onto the sidewall where you will never be able to use it (The common mistake is to use the 130/70-18 tire on a 2.50-18 rim....I made that mistake with my first tire on my Cafe bike as I followed the trend.....then I learned my lesson when the tire wore the center of the tire really quickly and I had tread on the sidewalls that had never touched the pavement). My current choice of tires for the Cafe is a shorter 90/90-18 on the front, it helps to quicken the steering as it is a light weight tire and helps to lower the front with the short sidewall (the 100/80-18 just looks too beefy to me after using the smaller tire). For the rear the 130/70-18 on a 3.50-18 rim looks really beefy and matches the current big back tire trend......a 120/80-18 on the 2.50-18 looks more vintage appropriate, is lighter weight and is plenty of tire for the Savage power and weight). Here is the Cafe' tire discussion thread I started....it is applicable to your Tracker discussion. There is a tire fitment guide for rim size vs. tire size: http://suzukisavage.com/cgi-bin/YaBB.pl?num=1435340395 |

For reference, the Norton Commando, the hot bike from the 60/70's used what we would now consider very skinny tires, but was really quick! 8-) https://silodrome.com/norton-commando-750/ |
