I know this is a very old post but this may be helpful to others who google search this topic. I recently found that the Yamaha TY80 shifter is an excellent fit for the Fantic 200 rear kick. If you use the original it is nice and short for those who move the pegs back and down. For those wanting an alloy option Yambits sells one for the ty80 that works but it is a little longer.

Its the forward riding position that I prefer.

No changes other than modern foot pegs will not be reversible. I tend to like a more forward position and just dislike the tiller effect. I have change stems on 2 ty175s and a TY Mono and have not regretted it. I always keep the stock items and convert back to stock if I stop riding it. Just personal preference. Probably because I came from a mountain bike background.

I have used Falcons on my TY builds and have been very happy with the feel. I was also thinking about going a sightly longer to steepen the head angle a bit more. Not doing anything crazy. Just some upgrades to the carb, bash plate, airbox, suspension, yolks and foot pegs. Most of the work is cosmetic and or fixing damage due to years of wear and tear. Luckily my head tube angle is still in spec.

The bike needs cosmetic work and some minor frame repair. Also looking to move the foot rests and add modern pegs. I have some new stems with steepened head angle on the way. I have experience with modern upgrades to TY 175s but this is my first twin shock Fantic. Not going to mess with steering angle beyond yokes, but may do some work on the front forks. I also plan to modify the gearing and add a new air box, carb and head pipe.

I just purchased a Fantic 240 trials that I intend to do a full restoration on. The bike came with NOS Marzochi shocks on the rear. are these worth keeping or should I replace with a more modern setup like Rockshox's?

Thanks for all of the positive responses. The swingers is from AJG. Needed to put the stickers back on. The bike runs and rides great and is a blast. I just started on second TY175 restoration and will post my progress. Have a great New Years!!

The bike is running great and it is a joy to ride. Last and final upgrade now complete. Its now on to bike number two, another TY175 build.

Finally finished and ready for its first event this weekend. BIG thanks To Jeff for all his help!

I have been distracted by my race car and racing season so little progress made over the past several months. Started moving the project forward again and should have it off the rack and on the trail in the next couple of weeks. Enjoy!

No clearance issues with shock body. Going to try the shocks in both positions once it is ready to ride.

Made some additional progress on my TY175 project. Motor now re-assembled and re installed along with triple clamps and mud guard.

Thanks, I will keep the thread updated with pictures as I make some more progress.

The frame and polished side covers have been powder coated so my hope is they will be a bit more durable than standard paint. Forks are wet sanded to a high polish so not paint o worry about. My friends frame with similar finish has held up well so I am hopeful. Graphics are factory type so should hold up as well.

Built to ride so it will definitely happen.

Not sure yet, I am just playing around with potential options. I modified the mounting posts to allow for easy repositioning. I am going to test the shocks clearence tomorrow to see if they will clear in the center location. If not I can easily move them downward to the lower location which is the intended location. Changing position can be acomplished in a couple of minutes and it will be interesting if change in location has a significant effect on handling and shock performance.

I am new to the site and the sport and motorcycles in general . This being my first post in the general forum I would post some pics of my project. In October, I attended my first trials event and ended the day hooked on the sport and with a 1976 TY175 purchased from a fellow competitor in the parking area. After getting it home I noticed a few items that needed some attention so I began to dig in. As often happens with projects, a light freshening has turned into a full resto-mod. The work below has been completed with some help and inspiration from friends (thanks Jeff!). Below are some pics of my progress, hopefully you will find them interesting. If you would like to see some earlier project pics, you can view them in my post in the introduce yourself section. Regards, Ed

The mods mimic the majesty frames where the hoops were cut. I looked at how the frame is likely to be loaded and I do not believe they add any structural benefits. If I sense any flex I will add a cross member near the fender tabs. I also intend to use a different fender and muffler, so the rear fender mount is not required. My goal for removing the hoops and all of the extra tabs and brackets along with the tubes under the sump was to reduce frame weight. For the sump I added a front cross brace salvaged from the rear sump bracket and shaped to fit. I added two 1/8" thick steel tabs on the cross bar the holds the rear engine mount to allow for attachment of the thicker flat sump plate. Finally I added some small additional gussets along with profiled end caps to the cut tubing ends to cosmetically clean up the frame. I plan to add an inch of material to the rear of the sump plate so it rests on the engine mount cross bar and will perforate it to reduce weight. Once it is back together I plan to ride it back to back with a stock TY175. I will also make sure I have a much more experienced rider do the comparison. I am not sure any of this makes sense but I enjoy the process and can do it all in my shop. Next step is powder coating.

After a significant amount of reading and a several conversations with bike setup experts, I believe that extending the wheelbase would improve certain aspects of handling such as traction on steep sections. If you compare the wheel base of the TY175 to other successful designs it is on the short side. Although this mod may increase the turning radius a bit, many feel it improves the overall balance. To accomplish this I purchased the shedworks plates and cut the old tabs off and welded the new plates in place. At the same time I purchased Tyoffroad shock relocation mounts to lower the upper attachment points laying the shock down like the Majesty frames. The advantage of this mod is supposed to be longer more progressive travel and steeper head angle. The other mods were implemented to reduce weight. Was any of this mandatory? No, but I got carried away and enjoy personalizing my rides. It is also important to note that I have a stock frame on hand that I can swap back too if I am not happy with the end result.

Hi, I am new to the sport this website and motorcycles in general. I participated in my first trials event this last October and decided to jump in with both feet. I am currently restoring and modifying a TY175 for the coming year and have a second restoration waiting in the wings. I have learned a lot already from this site and it has helped shape my project. I am new to trials bikes but have been building, wrenching and racing cars for several years. Below are some pics of my TY frame in process. Enjoy!
