3yrs ago I parted ways with my trusty KTMs and jumped onto the Yamahas... Starting first with a YZ250 that I built into the ultimate woods bike, it was 'almost' everything one could want. But it did lack the e-start, HO stator and 6spd, things that I really wanted as the ultimate machine. Then a new YZ450F made it into my garage which I built into a woods machine (the FX didn't exist at the time). All the power in the world so a 6spd wasn't needed. But I still lacked the button and fat stator. Shortly after a large crash and some broken body parts, I then moved to the new YZ250FX which has been with me the last year. Coming with a near perfect 6spd, a 100+W stator and the magic button it should have been near perfect. But I did want for more. The bike was heavier then it's competition, taller and underpowered, but overall probably the best beginner/average riders bike available. There is no question that the Yamahas could be anything you wanted. I had great success on all 3 bikes with near bullet proof reliability, fantastic motors, outstanding suspension and unquestionable race worthiness adding a few wins and multiple podiums to my resume. But... ...when KTM introduced their new 16 models, it was hard not to look over the fence to see if the grass was greener. Could my criterias be met? So on Saturday, I picked up a new 2016 KTM 350xcf. On paper, 'most' of all criterias are met. -6spd? Check! -Lightweight? Check! -Less power then the 450, but more then the 250FX? Check! -Magic Button? Check! -HO stator? Uncheck! So outside the stator, the 350xcf is looking pretty good on paper. Why not a new 250/300 2t? As mentioned in another thread, I rode a couple 300s and wasn't neqrly as impressed as I wanted to be. So why the 16 over the 17? Cost and cost alone was pretty much the deciding factor. Outside of the AER the bikes are virtually identical. With nearly a $2000 savings between the 2 it left money I table I could spend elsewhere. And after talking with a bunch of tuners, at worst if I can't get the 4CS working, the extra money can be used for another fork options such as a KYB internal setup, or CV cartridges. So, I started this thread to kind keep my trials and tribulations on update for you wonderful folk on TT. Adding my opinion, impressions, mods, results and all that other jazz... Initial impression while sitting on the stand seem good. I've been tearing it apart greasing everything, weighed a few parts and giving it the look over. I question if the bike is built for long haul. It seems extremely well put together, but almost too well. The plastic lines blend well with no areas for hangups as well the bike feels thins, especially compared to any current Yamaha 4t. The bike also feels low and long, where as the Yamaha 4ts feel tall and short. Equally so the bike feels light and easy to throw on a stand with well placed grab handles.

Hi, was hoping to get some help with choosing new tires for my DRZ400SM 2005, I have a some on my mind, but there are a few problems. So my bike has Excel rims, front 3.5"(RK EXCEL J17 M/C X MT3.50 DOT 181 JAPAN 1 05), rear 4.5"(RK EXCEL J17 M/C X MT4.50 DOT 181 JAPAN 12 04). I was hoping to get some suggestions for some 90/10 asphalt/dirt tires for mostly riding around, some twisties, but no track or very hardcore riding, so longer lasting might be better than super sticky. I already have a set of S wheels for real dirt riding, but still need the SM ones to not be completely awful on dirt as there are occasional times I have to go on dirt with them(For example a kilometer every time I go front or to my house) I was looking at the Michelin Pilot Power 3, but the only choice for the rear is 160/60, which I have heard is too wide. Another one I was looking at was Michelin Pilot Road 4, any experience with it? Thanks for your help, have been surfing the forums for a decent time and seen how helpful people are.

Provides Increased Range of Versatility for All Skill Level of Riders SAN DIRGO, CA – January 17, 2016 – (Motor Sports Newswire) – Pirelli introduced today its latest motocross tire offering with the unveiling of the all-new SCORPION™ MX32™ PRO rear motocross tire. The debut took place inside Petco Park, the site of the second round of the 2016 Monster Energy Supercross series. Race-winning BTO Sports/WPS/KTM racer Andrew Short, who played an instrumental role in the development of the MX32 PRO, was on-hand to provide a glimpse into the on-track testing and development that went into the new tire that boasts an incredible range of versatility for riders of all skill levels. In addition to Short, Pirelli-supported race teams, test riders and engineers spent countless hours developing the new MX32 PRO before unveiling the design that provides maximum performance and durability. Whether it’s recreation or competition, wet or dry, the MX32 PRO is sure to outshine the competition. “The entire Pirelli team has put an extensive amount of time into the development of the new MX32 PRO rear tire,” said Pirelli motocross tire technical specialist, Doug Schopinsky. “The endresult is a highly versatile tire that performs extremely well in a variety of conditions and across a wide range of skillsets.” Boasting larger block sizes, or “knobs”, the MX32 PRO increases the tread contact area and improves durability on both MidSoft and MidHard soil types. Large void area between the tread pitches assures good self-cleaning. Modified side knobs feature “dimples” to optimize lean angle grip and stability for maximum traction and control in turns. Casing depressions, including the iconic Scorpion mark, increase plant and ride comfort, while the tread spacing and crown radius profile broaden the range usage. The MX32 Pro rear tire will be available in 110/90-19 (MSRP $139.89) and 120/80-19 (MSRP $145.07) sizes and hits authorized Pirelli tire dealers on April 1, 2016.

So I found the tires I want to buy however they don't seem to have them in the stock size the bike came with. I am new to dirt bikes and don't know what the size difference does as far as handling goes. What size are you guys running that have the MT21's?
