The tbr7 has tires mainly for road. It was actually my main choice since I am commuting.
My commute is only 6 miles rt. (lol)
I, at the time, searched ebay and amazon for the lowest price/quickest shipping.
amazon items
42 teeth rear sprocket
130 link HD chain
Jets for Stock Carb (only main will fit, not pilot tho
ebay
17 teeth front sprocket
full exhaust just had to make bracket for muffler section and drill hole larger for mid section and also flange holes were made larger
NGK D8EA plug
Here you can see my running costs. $200 for upgrades, under $100 for lubes/oils/etc and $200 for full gear HWK or Hawk brand.
Everything brand new except I saved maybe $15 with the Cold Weather jacket but it was like new. Received it and I dont think it was ever worn.
-ORDERS/MODS- $197
$80 exhuast (ebay)
$12+22 sprockets f(ebay) r(amzn)
$19 chain (amzn)
$12 ext lights (amzn)
$10 jets (amzn)
$7 spark plug (ebay)
$7 storage bag (wm)
$28 tach (amzn)
-tools/oils- $90
$8 feeler (ebay)
$15 fork oil (ebay)
$10 loctite (ebay)
$29 lube/grease (amzn)
$14+14 rotella (wm)
-gear- $205
$40 helmet (amzn)
$45 cold jacket (ebay)
$50 warm jacket (ebay)
$60 pants (ebay)
$10 gloves (ebay)
So just under $1700 shipped to door with the $500 gear/mods added,
that puts me at $2200 total -- notary and tax (wont mention since that will vary with state)
Wifey doesnt work, so rainy days I just drive the fam car to work.
